Abstract Banglalink is one of the biggest mobile phone companies at Bangladesh. It started its operation in February 2005. Previously it was known as Sheba telecom Pvt L. T. D that had been GSM (Global Service of mobile) Service in Bangladesh since 1998. Orascom Telecom brought 100% share of Sheba telecom in 2004 & gave it new name as Banglalink. Every company’s existence depends on its customers.

So, each and every company tries to satisfy & retain its customers providing attractive services. So, we’ve conducted our research on the customers of Banglalink to find the satisfaction level towards the company. As the satisfaction level indicator we used the following contents: Today’s market is highly competitive. So, every time competitors try to find the weakness & want to beat those points. So, the company should take customer feedback on continuous basis. That’s why excessive market research is required. Finding the customer’s demand & recommendation will help to take right decision.

In August, 2006, Banglalink became the first company to provide free incoming calls from BTTB for both postpaid and prepaid connections. On August 20, 2008, Banglalink got past the landmark of 10 million subscriber base. Organization overview In Bangladesh, Banglalink aims to understand peoples’ needs best and develop appropriate communication services to improve peoples’ life and make it simple. All our work is aimed towards meeting our vision. All members of the Banglalink family are highly passionate individuals, fully committed to achieving the vision that we have set ourselves.

Our customers’ needs matter most to us- making their life simple and improving it is all we want. To ensure our vision is achieved, we have set ourselves a few values, we want to be

•  Straight Forward
• Reliable
• Innovative
• Passionate

All the Banglalink family members have one thing in common- a passion to serve to go that extra mile, so that you can have the best possible service Investing in the future of Bangladesh. The biggest barrier today for people is the cost of handsets. We will strive to lower the total cost of owning a mobile.

We are here to make a difference in people’s lives by providing affordable and reliable connectivity will strive to connect people and link their lives by listening to them and by understanding their needs. We are here to help you speak your language. Research Objective Our research objective is to find out the satisfaction level of banglalink customer. The purpose of the study is to provide a specific and accurate definition of the overall PR & communication department of banglalink. As a 2nd largest company how they are managing the public relations.

• Provide an overview of the banglalink To identify the factors influencing on the marketing plan of the company
• To find out the strategies need to implement for achieving its long term goal.
• To measure and improve your performance  To know customers are satisfied or not by taking service
• To supply products at competitive prices.
• To explore public relation activities in the market.

Limitation of the study

Every work when started that to face some limitations. So in our research we face some problem. Our main limitation is time. Because we do not enough time for make this project but we tried our label best to make this report is a good one.

Our second limitation was our different class schedule that why it was creating some problem when we making the survey. Our third limitation was financial fund because we are student. Significance of the study: Our research is based on the satisfaction of banglalink customers. We think from our research banglalink company will get more benefits. From our research banglalink customers relationship management can get some information about their customer’s satisfaction. In sort they can know from our research how they provide their services for their customers and how the customers react their services.

So when banglalink management observes our customers satisfaction research result based on this result they can take their decision.

Scope of Research

Research type

This research is a type of descriptive study which defines the relationship between the customer satisfaction and the banglalink management. Here the customer’s satisfaction is about the measurement of the wants of banglalink customers. On the other hand, banglalink customers are the population of our project as well the respondent. Those customers who are using the banglalink sim card and use their given services.

Sample

Here the sample means the customers of banglalink those who are using the banglalik sim card and use their given services. Measurement: Basically we are come through a solution of our problem with Survey Questionnaire. And we make this Questionnaire to identify how much the customers of banglalink are satisfied. Statement of Problems: We have a solution of our problem by briefly discussed and we conducted a survey on the students group of AIUB. For that, we arrange a set of questionnaire and seeking some help from some loyal customers of banglalink.

And those customers are basically ongoing users or once used Baglalink connection and also those customers who are use from their beginning. How is their satisfaction as a customer of banglalink in their real experience? Then we are the seven members work jointly to complete a strong semester project on customer satisfaction of Banglalink whatever we get acquire knowledge from our honorable course instruct Dr. Mamun Habib during this whole semester.

Research Hypothesis

Hypothesis means the assumption. We are assuming some questionnaire to our respondents and try to analysis those.

This research is coming through “One-Tailed Test” that is defined as the direction of the project. For example is that (Low/High) HO: Customers satisfaction would be greater than, less than their expectation Ha: Customers satisfaction would be less than, greater than their expectation Chapter -4 Research Methodology Methods of Research Used Difference types of research technique we are selecting descriptive research because we are finding customer satisfaction of Banglalink based on primary data. How many people are satisfied or not. Descriptive: Describes characteristics of a population or phenomenon, objects, organizations.

Some understanding of the nature of the problem. Respondents & Sampling Procedures Population is any complete group of people, sales territories, stores . Sample subset of a large population we are select people among university student they are satisfy or not. There are three types of sample size we select formula for known and unknown population because firstly select BANGLALINK service users or not. Probability sampling we use to get our respondents. This process has to each element of population an equal chance to be selected . Known, nonzero probability for every element.

Different categories sampling among these category we select simple random sampling. Simple random sampling: A sample procedure that ensures each element in the population will have an equal chance of being included in the sample. Research Instruments: Here different tools for questionnaire survey:

• Simple Attitude scale
• Category scale
• Likert scale
• Semantic scale
• Numerical scale
• Constant sum scale
• Stapel scale
• Graphical Rating scale
• Graphics rating scale stressing visual communication From these survey scales we used Five point Likert Scale for conducting our survey.

We asked different questions based on BANGLALINK customer care service and collected answers through likert scale. Statistical Treatment of Data SPSS (Statistical Package for Social Sciences): Based on SPSS we complete our statistical treatment. Descriptive analysis: Demographic information of respondents and estimate proportion among respondents.

Presentation of data and discussion of results

There are several tools available for data analysis. Like Excel, SPSS, AMOS, LISREL etc. For the collective data analysis we have used MS Excel & SPSS (Statistical Packages for the Social Sciences). The respondents’ percentage based on gender: [pic] “Banglalink’s call rate is reasonable with compare to other operators”: pic] “Banglalink provides good services at their customer care centers:” [pic] Banglalink’s network system is very strong: [pic] Banglalink has huge opportunities to become market leader of Telecommunication Industry: [pic] Chapter-6 Summary, Conclusion & Recommendation Summary of the findings: Banglalink is one of the largest telecom companies in Bangladesh. After commencing their operation in Bangladesh, Banglalink captured a large number of customers. So, other mobile operators’ customers switched the brand. But now from our research we are finding a complete different scenario.

In person we are the customers of Banglalink. So, we conducted our research on our friends & the different students’ group of AIUB to get quick access to the information. Our research shows that for the last few years Banglalink’s performance is falling gradually & failing to meet the customer’s requirement.

• Most of our respondents have agreed that Banglalink’s call rate is not so high with compare to other operators. But there is also a larger group of respondents who didn’t comply with this statement.
• Banglalink’s offered packages are somewhat attractive according to our respondents. A major portion of respondents have agreed that Banglalink is good at promotional activities.
• Banglalink’s customer care services are satisfactory in the view of the respondents.
• Banglalink has developed its internet facility recently. So, the current customers are satisfied with new services.
• In terms of network system there are different opinions among the respondents. In the cities & towns the network is good, but at villages or remote places this service is very bad. As our all respondents are from Dhaka city, the respondents are satisfied with the network service. Banglalink has somewhat contribution in social development regarding our respondent’s view.
• There are a few large telecom companies in our country. For the last few years GrameenPhone has been holding the market leader’s place. From our research we can see that Banglalink has no possibilities to become the market leader. Conclusion: In the country Banglalink has come with the mission of “Din Bodoler Pala”. At their market entrance they showed huge possibilities to become the market leader. They captured the most of their customers within their first two years of operation.

But with times customers are leaving Banglalink. Recently a new operator has penetrated into the telecom industry. Besides the former operators are diversifying their packages & offerings. But Banglalink had failed to cope up these new changes in the industry. They also offered some new packages, but those are not sufficient to cope up the situation. To attract different group of customers, Banglalink should take different approaches to gain new customers. Banglalink is a large organization & they are skilled & well experienced to take any decision. Our research shows that dissatisfaction is generating among the customers of Banglalink.

Introduction:

Natural fibre has been in a broad usage since the development of the human race. They had got broad acceptation in communities for their flexibleness and strength. Recent tendencies in the country of fibre reinforced complexs have drawn a twine in utilizing these natural fibres as their support. The natural fibre imparts lower lastingness and lower strength compared to glaze fibres. However, low specific gravitation consequences in a higher specific strength and stiffness than glass. Natural fibres offer good thermal, dielectric and acoustic insularity belongingss along with easiness in processing technique without have oning of tools.

Most of these fibres are produced in developing states like China, India and Brazil etc. In a historical position complexs like straw reinforced walls, bows and chariots made of pasted beds played of import functions in their endurance. Though many of these fibres are limited to their epidemic parts due to high local demand for many old ages, coming of man-made fibres have affected the market of natural fibres. After being entirely used for their electromagnetic belongingss, utilizing complexs to better the structural public presentation of ballistic capsule and aircraft became popular in last two decennaries of the old century. Particularly, increased constrains and future environmental route maps, have been emphasizing automotive industries to diminish their C pes prints. These rigorous steps have become blessing to the lagging natural fibre industries, and thereby making new challenges for research workers in happening beginnings of fibre, fiction techniques and applications of natural fibres. The easy handiness of natural fibres and fabricating have motivated research workers worldwide late to seek locally available cheap fibres and to analyze their feasibleness of support intents and to what extent they satisfy the needed specifications of good reinforced polymer complexs .

Many surveies proved them to be possible rivals to man-made fibre to some extent. After reexamining the bing literature available on natural fibre complexs, assorted writers had put attempts in planing complexs based on the demands of composite industry. There has been a broad assortment of literature available on natural fibres such aspen, abaca, bagasse, bamboo, banana, coir, day of the month thenar, flax, henequen, isora, jute, silk cotton, deccan hemp, oil thenar, Ananas comosus, ramee, sisal, etc. , . Natural fibre complexs provide comparable specific strength with that of man-made fibre complexs, due the low denseness offered by natural fibres . There are many parametric quantities which affect the public presentation of a natural fiber-reinforced complex. Chemical alteration improvesA fiberA matrix adhesion, their consequences and effects on the physical belongingss ofA complexs . Aspect ratio has a considerable consequence on composite belongingss, hence it is of import to conserve fiber length every bit much as possible during composite processing operations . Mechanical belongingss of the composite vary with assorted sums of fibre volume ratio. But there have been a really few documents covering with Palmyra fibre, the present fibre of our involvement.

The Borasseus Flabellifer is a tall and vertical thenar, and can populate 100 old ages or more and make a tallness of 30 m, with a canopy of big, fan-shaped foliages several twelve found distributing 3 metres across . Each and every portion of the tree is a noteworthy socio-economic value for people in Southern India. The mid-ribs of the foliages and the fibres from their chaffs are used in doing industrial coppices and brooms. The fibre has good opposition to clash and heat, and will defy many chemicals and dissolvers. The denseness of toddy palm ( 0.7 gm/cm3 ) is least among all known natural fibres that are being commercially used in fabricating natural fibre complexs. This is extremely favourable belongings from the position point of light-weightiness. The present complex can happen extended application in non-structural, low-performance utilizations. Hence, the toddy palm fibres are most suited for doing support in green composite stuffs.

The present research focuses on the survey and consequence of procedure parametric quantities on the tensile strength of short and indiscriminately oriented palmyra natural fibre reinforced complexs. The decisions drawn from this is that, a successful combination of procedure parametric quantities consequences in the betterment of mechanical belongingss of the composite. In future, complexs will be manufactured even more harmonizing to an integrated design procedure ensuing in the optimal building harmonizing to parametric quantities such as form, mass, strength, stiffness, lastingness, costs, etc. The developed mathematical theoretical account will be able to demo the influence of a design alteration on each one of these parametric quantities ( here strength ) .

Response surface methodology:

Response surface methodological analysis ( RSM ) began with the work of Box and Wilson in the Journal of the Royal Statistical Society [ 26 ] . That work was motivated by the demand to run experiments expeditiously, by a proper pick of design, and to find operating conditions on a set of governable variables that give rise to an optimum response. The cardinal thoughts in the classical RSM are developed utilizing additive multinomial theoretical accounts, chiefly first-degree and second-degree theoretical accounts, with uninterrupted response variables assumed, for the most portion, to be independently and usually distributed with changeless mistake discrepancies. This method has gone through several phases of development that are aimed at doing it more applicable to wider experimental state of affairss.

RSM is a aggregation of mathematical and statistical techniques that are utile for the mold and analysis of jobs in which a response of involvement is influenced by several variables and the aim is to optimise the response. For, illustration, if the experimenter wishes to happen the degrees of two input variables, x1, x2 which maximize the output [ y ] of the procedure, so the procedure output is stated as:

where Iµ represents the noise or mistake observed in the response Y. If the expected response is denoted by E [ y ] = f [ x1, x2 ] = I· , so the surface represented by I· = f [ x1, x2 ] is called a response surface. If the individual input variable can be related to the end product variable so it is known as response curve and if the two input variables relate to the end product variable so it is known as response surface. In common pattern, response surfaces are expressed diagrammatically and visualized through single secret plans, contours and 3D surface graphs.

Specimen fabrication:

The petioles of Asiatic Palmyra tree were soaked in a H2O retting armored combat vehicle for 45 yearss. After 45 yearss, the fibre can be extracted from the chaffs manually. These long uninterrupted fibres are washed exhaustively in plentifulness of clean H2O to take the excess waste .

Alkali treatment:

The obtained fibres were divided into three parts of equal weight. These three groups of fibre were treated with 5 % NaOH solution for different clip continuances. The first group is treated for 2 hours, the 2nd for 4 hours and the 3rd for 6 hours. Chemical intervention with NaOH removes wet content from the fibres thereby increasing its strength. The chemical intervention besides clears all the drosss that are bordering the fiber stuff and besides stabilizes the molecular orientation. After alkali intervention, fibres were washed exhaustively in the distilled H2O and were dried for one twenty-four hours at room temperature.

Then these long fibres were cut into short fibres of different lengths ( 3mm, 5mm and 7mm ) . The fibres which were treated for 2 hours with NaOH are cut into equal sums of 3mm, 5mm and 7mm fibres severally. Similarly, the fibres which were treated with NaOH for 4 hours and 6 hours were besides cut into short fibres. Therefore nine different samples of fibre were prepared which vary in fibre length and alkali intervention hours.

Prepation of composites:

A rectangular wooden board of 300mm, 300mm was taken and wooden forms of thickness 4mm were fixed on these wooden boards with the aid of nails. These wooden forms were placed so that a infinite of 150mm, 10mm, and 4mm was obtained. After the molds of needed dimensions were prepared, wax was applied to the interior sides of the molds for easy release of the complex without lodging to the mold walls. Then the matrix was prepared by blending the hardener to epoxy. The epoxy and the hardener ratio were maintained at 10:1. To acquire good cured and a standard quality specimen, the epoxy and hardener must be assorted swimmingly and easy for about 10 proceedingss. Initial bed of the mold was filled with the epoxy rosin and hardener mixture and so the appropriate measure of fibres was placed such that epoxy mixture wholly spread over the fibres. Again, epoxy mixture was poured on the fibre. Therefore, the starting and stoping of the beds were of epoxy rosin. A fictile releasing house was placed on the top of the uncured mixture. Before using compaction, attempts were made to take all bubbles with roller. Finally, the compaction force per unit area of 0.05 MPa was applied equally and cured for 24 hours at room temperature. In this manner, specimens incorporating different volume fractions of fibre were prepared. These specimens were cured in the hot air oven at 600 C for 2 hours. Specimens incorporating different fibre volume fractions such as 20 % , 30 % , 40 % were prepared and 27 specimens were prepared. The specimen  is prepared with the dimensions of 150mm length, 10mm breadth and 4mm thickness harmonizing to ASTM D 3039-76 is used for experimentation.

Mechanical testing of fiber-reinforced composite:

The most basic mechanical trial is the tenseness trial. For most structural stuffs, the tensile belongingss are indispensable elements of the stuff design allowable. The complexs specimens were tested as per ASTM criterions. The tensile testing was done as per ASTM D 3039M with the aid of INSTRON-6025 theoretical account Universal Testing Machine at a crosshead velocity of 2mm per minute and consequences were analyzed to cipher the tensile strength of composite samples.

Description of proposed methodology

The control factors considered for experiments are alkali intervention clip, fiber length and fibre volume per centum while tensile strength is considered as the end product response.

The process of response surface methodological analysis comprises the undermentioned stairss:

• Plan a series of experiments for equal and dependable measuring of the response of involvement.
• Develop an empirical or mathematical theoretical account of the 2nd order response surface with the best adjustments.
• Find the optimum set of experimental parametric quantities that produce a upper limit or minimal value of response.
• Represent the direct and the synergistic effects of procedure parametric quantities through two and three dimensional secret plans.

Conducting the experiments

The executable scopes of the procedure control variables considered are listed in Table 4.2. These values correspond to the conditions at which there is maximal consequence on tensile strength as reported by other writers for different natural fibres.

The belongingss of Asiatic Palmyra fibre reinforced complexs with different fibre lengths, clip continuances of Alkali intervention and fibre volume per centums under these conditions, the probes are presented in the undermentioned Tables 4.3, 4.4 and 4.5. Sample of tensile trial studies are shown in Fig. 4. The tensile strength of the specimen made of epoxy and hardener is 12.44MPa.

Development of empirical models

The informations collected from typical experiments refering to end product responses, Tensile Strength from Tables 4.3, 4.4 and 4.5 are used to implement the proposed methodological analysis. The demand in developing the mathematical relationships is to associate the tensile strength to the procedure parametric quantities thereby easing the optimisation of the procedure parametric quantities. Design Expert, 8.0v [ 31 ] , statistical analysis package, is used to calculate the arrested development coefficients of the proposed theoretical accounts.

The interaction effects of the procedure parametric quantities and tensile strength are important and hence the 2nd order theoretical accounts are postulated. The multinomial is fitted and the relationships obtained for the end product responses are given below:

Adequacy trial:

The developed empirical theoretical accounts are tested for their adequateness utilizing the undermentioned trials:

Analysis of Variance [ ANOVA ] :

ANOVA is carried out for the quadratic response surface theoretical accounts. The statistics of ANOVA for Tensile Strength is given in the Table 4.6. In instance of tensile strength, it can be observed from Table 4.6 that the value of “ Probability & gt ; F ” for the theoretical account is less than 0.05, which indicates that the theoretical account is important [ 28 ] .

Multiple arrested development coefficients:

To look into whether the fitted theoretical accounts really describe the experimental information, the multiple arrested development coefficient [ R2 ] is computed. R2 statistic is defined as the ratio of variableness explained by the theoretical account to the entire variableness in the existent experimental informations and is used as a step of goodness of fit . If R2 attacks to integrity, the better the theoretical account fits the experimental information. In other words, it is the proportion of fluctuation in the dependant variable [ response ] that can be explained by the forecasters [ factor ] in the theoretical account. From Table 4.6, R2 for tensile strength is found to be 0.9276. This shows that the second-order theoretical account can explicate the fluctuation in tensile strength up to the extent of 92.76 % .

The adjusted R2 efforts to give a more appropriate value to gauge R2. Adjusted R2 can be computed utilizing the expression 1- [ [ 1- R2 ] * [ N-1 ] / [ N-k-1 ] ] , where N is the figure of observations and K is the figure of forecasters When N is little and K is big and there will be a much greater difference between R2 and adjusted R2 [ because the ratio of [ N-1 ] / [ N-k-1 ] will be much less than 1. By contrast, when the figure of observations is really big compared to the figure of forecasters, the value of R2 and adjusted R2 will be much closer because the ratio of [ N-1 ] / [ N-k-1 ] will near 1. From Table 4.6, adjusted R2 for tensile strength is found to be 0.8915. It can be observed that the values of R2 and adjusted R2 are much closer to each other.

The developed mathematical theoretical accounts are farther checked for their adequateness utilizing normal chance secret plan of remainders. The diagnostic secret plans are drawn to look into whether the informations are usually distributed and for any premise is violated. Therefore, the normal chance secret plan of remainders for the responses, tensile strength is plotted.

Normal chance secret plans are used to measure whether informations come from the normal distribution. The statistical process makes the premise that an implicit in distribution is normal. Thus normal chance secret plans can supply confidence that the premise is justified, or else supply a warning of jobs with the premise. An analysis of normalcy typically combines normal chance secret plans with hypothesis trials for normalcy. In a normal chance secret plan, if all the information points autumn near the line, an premise of normalcy is sensible. Otherwise, the points will swerve off from the line, and an premise of normalcy is non justified.

Decision

The proposed work is on the survey and consequence of procedure parametric quantities on the tensile strength of short and indiscriminately oriented toddy palm fibre reinforced complexs. The experimental probe on mechanical behavior of palmyra fibre reinforced complexs leads to the undermentioned decisions: Tensile strength ( TS ) , of the toddy palm fibre reinforced composite stuff is greatly influenced by alkali intervention clip, fiber length and fibre volume fraction. The quadratic theoretical account developed by RSM can be used to foretell the tensile strength of the toddy palm fibre reinforced composite stuff at 93 % assurance degree. But the cogency of the theoretical account is limited to the scope of parametric quantities considered for the probe. The truth of the developed theoretical account can be improved by including more figure of parametric quantities and degrees. Further, mathematical theoretical accounts can be developed by taking multiple responses, with different scopes of procedure variables and the composite design can be optimized based on the demand of the clients.

For your convenience, each question is given followed by the appropriate answer and an explanation of the correct response. Work your way systematically through these, comparing It with your own answer. Even If you chose the correct alternative, you may find that the explanations we give are useful. Try to understand the explanations. Many of the Items measure Insight, not Just factual knowledge. You will not pass this course if you try and memories the questions and answers!

Question 1

The goal of quantitative research in psychology is best described as aiming to –

1. Polo appropriate statistical tests which can be used to determine the relationships among psychological variables that occur at a level greater than chance

2. Develop theories that helps us to explain human experience and behavior

3. Formulate clear hypotheses based on insights about human experience and behavior

4. Convert theoretical constructs into measurable variables through personalization

Answer: Option 2 gives the correct answer. The goal of research Is to develop theories which can explain aspects of human behavior and experience.

Options 3 and 4 refer to stages In the process of doing initiative research but these are not the goals of the research. The goal of the research Is also not to develop statistical tests, as Implied In option 1 . These tests are developed by statisticians and are used by researchers in social and other scientific research, but developing the tests is not part of the goal of the research.

Question 2

A psychologist believes that personality factors such as ability to get along with other people in a team are likely to have on influence their success in a team sport.

To investigate this, she draws a sample of participants in competitive sport, comprising f soccer players, hockey players and cricketers from various sports clubs. After evaluating their performance on an appropriate psychometric test, she delves players from the three categories of sports Into two groups: those who have good social skills and those who tend avoid social contact. She then uses evaluation forms, based on interviews with different sports experts, to assess the actual sports performance of the members of the sample.

The dependent variable in the study is – – – – – and the independent variable is – – – –

1. Measured sports performance; social skills

2. Type of sports; social skills

3. Social skills; measured sports performance

4. Social skills; type of sports

Answer: Option 1 is correct. The researcher wants to determine whether sports performance (a measurement of how well a specific sports participant performs) depends on social skills. This Implies that the construct ‘social skills’ Is the Independent variable which Is varied to see how it affects the dependent variable, the measurement of sports performance. The population from which the sample was drawn (the participants that were involved), but in the context of this scenario this variable is not being investigated here. It would be possible to compare the three groups but this would not answer the research question.

Question 3

Consider the following statement: “That phase of sleep during which brain rhythms resemble those of an alert person is called paradoxical sleep or rapid eye movement (ERM) sleep. ” This statement is a – – –

1. Conclusion based on empirical research

2. Operational definition

3. Search hypothesis

4. Inference based on observation

Answer: Option 2 is correct. The statement gives a definition of ERM sleep in terms of the measurement of brain waves (which can be done with an EGG machine). Since it is simply a statement about what the expression ‘paradoxical sleep or rapid eye movement (ERM) sleep’ means, it is not a conclusion, hypothesis or inference, as suggested by the other options. 6 Questions 4 to 6 are based on the following research scenario. A psychologist wants to study how aspects of motivation can influence people’s productivity in their work.

She reads an article which claims that an important aspect of motivation is locus of control, which distinguishes people who are driven by their own personal ambition from those who act by conforming to a social group. To test this idea, draws a sample of 100 workers from a number of companies in the information technology sector. She divides the workers into two groups, those with an internal locus of control and those with an external locus of control, based on an appropriate psychometric test. She then uses Job evaluation forms to assess the actual work performance of the workers in the two groups.

Question 4

Which of the following gives the best expression of the hypothesis that the researcher wishes to test?

1 . Motivation affects the productivity of workers.

2. Internal locus of control is related to high productivity.

3. The Job performance of workers is influenced by locus of control.

4. Motivation of workers is influenced by locus of control.

Answer: Option 3 is correct. Option 3 is the clearest expression of an appropriate research hypothesis. Option 1 is too vague: ‘motivation’ is probably too complex to be captured in a single construct.
Option 2 is too specific: it is not clear from the information given in the scenario whether internal or external locus of control can be expected to lead to higher productivity. ‘Locus of control’ is regarded as an aspect of motivation (according to the scenario), not as a separate construct (or variable) that can be compared to it, so option 4 is also wrong.

Question 5

Given that research is an investigation of a relationship between (two or more) constructs, which of the following constructs have to be compared to do this (b) motivation (c) locus of control (d) Job evaluation forms (e) people who work in the information technology sector

1. A) and (c) 2. (a), (b) and (e) 3. (a), (c) and (e) 4. (c) and (d)

Answer: The correct alternative is option 1 . ‘Locus of control’ is the specific aspect of ‘motivation’ that is being studied, which excludes option 2. In this particular context, ‘people who work in the information technology sector’ is part of the definition of the population that the researcher chooses to study, not a construct that is being compared to another, so option 3 is incorrect. Option 4 is incorrect because ‘Job evaluation forms’ are the instruments used to measure the construct ‘Job performance’, and not a construct as such.

Question 6

The dependent variable in the study is – – – – – and the independent variable is –

1 . Job performance; locus of control

2. Locus of control; motivation

3. Job performance; productivity

4. Locus of control; Job performance

Answer: The dependent variable is the one that is predicted or explained, and the independent variable is manipulated to see how it affects the dependent variable. In this study the researcher tries to predict Job performance with the aid of locus of control. In other words, the researcher is trying to see if Job performance depends, to a significant degree, on locus of control.

Option 2 is wrong because locus of control is the aspect of motivation that is being studied. In a similar way, Job performance is equivalent to productivity, which excludes option 3.

Question 7

In scientific research, the word theory refers to a(n) – – – – –

1. Reasonable guess or creative insight which seems to explain a phenomenon

2. Method to make the constructs which are involved in a phenomenon visible through a process of personalization

3. Investigation or procedure which is performed to determine the relationships among variables

4. Explanation of why the observations that were made are as they are, or are related in the way that they are related

Answer: Option 4 is correct. As explained on page 4 in the Guide for PECCARY, a theory is a framework for facts: it s the explanation of why the facts (I. E. Observations, measurements) are as they are, or are related in the way in which they are related, based on empirical investigations. Option 1 is a description off hypothesis, but this is often how the word theory is option 3 is a description of a process such as an experiment by which a theory can be evaluated but not to a theory as such.

Question 8

Consider the following statement: “The experience of strong emotion is accompanied by physiological reactions such as an increase in heart rate”. This statement can be viewed as a research hypothesis because it –

a) makes a prediction that can be tested by observation

(b) describes a possible relationship between variables

1. (a) but not (b) 2. Both (a) and (b) 3. (b) but not (a) 4. Neither (a) nor (b) 8

A psychological hypothesis formulates a testable empirical claim, that is, a prediction which can in principle be observed, and this usually involves postulating a relationship between two or more variables.

Question 9

A psychologist uses a psychometric test to study the intelligence of school children. Intelligence is the – – – – – variable and the psychometric test represents the – variable in this study.

1. Independent;

2.dependent manifest; operational

3. Dependent; independent

4. Latent; manifest

Answer: A hidden or underlying (latent) aspect of a construct has to be made visible (manifest) to be observed. ‘Intelligence’ is a latent variable because it cannot be observed directly. The results of the psychometric test can however be observed directly and can therefore be regarded as the manifest variable.

Note that the test result is the measurement by which intelligence is made visible, so these are manifestations of the same construct (or variable), only in one form it is observable (manifest) and the other form it is hidden (latent). Dependent’ and ‘independent’ refer to relationships between two different variables, so options 1 and 3 are both incorrect. The psychometric test is the operation by which the variable ‘intelligence’ is measured (or ‘personalities’), but you would not refer to the test or test result as an ‘operational variable’, so option 2 is also not correct.

Question 10

An industrial psychologist wants to investigate the levels of assertiveness among different categories of workers in a large company. He draws a sample of 200 workers and then divides them into managers, clerical workers, technical workers and manual errors with the intention of getting each participant to do a test to determine their level of assertiveness. The division of workers into these four groups represents a measurement on a – level.

1. Nominal

2. Interval

3. Asia

When numbers are used to allocate people or objects to categories or groups with no implication of ‘intensity or ‘ordering related to the size of the number, it is referred to as a nominal level or nominal scale of measurement. Note that while one may presume that ‘managers’ have a higher rank than the rest and perhaps ‘manual workers’ can be said to have a low rank, there is no obvious way to decide whether lyrical workers have a lesser ‘rank than technical workers or the other way round, as it would depend on the specific types of work that they do.

A senior clerk can outrank a Junior technician, and vice versa. (Nominal and other scales are explained in Appendix B of the Guide). PECCARY/201 9 Question 11 If a pupil will be chosen to go on a field trip from a class of 13 girls and 17 boys, what is the probability that Joanne (one of the 13 girls) will be chosen, given that a girl will be selected? 1. 1/13 2. 14/30 3. 1/30 4. 1/17 You have to use the basic formula for probability: We know that there are 13 possible outcomes (any one of the 13 girls can be selected) and we also know that there is only one favorable’ event Anyone being selected).

Peoples have different sentiments about vitamin E acquisition. Some people think that e-learning is advanced and it reduces the clip and distance barriers of instruction while the other group thinks that e-learning leads to feelings of isolation and defeats ( Handzic & A ; Ho-hur, 2005 ) . “ E-learning can be defined as utilizing web engineerings to make, foster, deliver and facilitate acquisition, anytime and anyplace ” ( Liaw, 2008 cited in Duan et.al. , 2010 ) . Due to globalization corporations have to cover with more complex and unsure state of affairss today. To last and win in this environment the administrations have to maintain up with the gait and have to be more advanced and efficient ( Handzic & A ; Ho-hur, 2005 ) .

It is of import to maintain the employees up-to-date non merely in the engineering but besides with the deductions which use the engineering and output for more efficient and effectual working ( Newton & A ; Doonga, 2007 ) . Corporate e-learning can be done in the signifier of e-training. Newton ( 2007 ) & A ; Doonga ( 2007 ) define Entraining as ‘an environment in which preparation or direction in a scope of accomplishments or techniques can be developed utilizing computing machine engineering ‘ . The intent of this paper is to place the benefits & A ; restrictions of corporate e-learning to administrations. Corporate E-learning is the hereafter of the concern universe. Corporate want to salvage more and more costs by holding more corporate e-learning instead than directing their employees to different locations for acquiring the needed preparation.

A Literature reappraisal &  Secondary Data:

The literature reappraisal will discourse the assorted advantages and restrictions of e-learning. The literature reviewed considers both qualitative and quantitative analysis in their research. The intent of the literature reappraisal is to happen spreads in the survey that has been conducted on e-learning. This includes benefits, restrictions and intent of e-learning.

Following are the benefits of e-learning:

Technological alterations increase the speed of work environment:

“ Technology has changed the manner people live, work, believe, and learn ” ( Urdan & A ; Weggen 2000 ) . The work force of today has to be on their toes to acquire a contract, to accomplish marks and all the challenges that come their manner. They have to understand a batch of information in a short p of clip. The rate at which new merchandises and services are introduced in the market is excess ordinary. “ As production rhythms and life ps of merchandises continue to shorten, information and preparation rapidly become disused ” ( Urdan & A ; Weggen 2000 ) . The preparation directors have to present the services more expeditiously and rapidly. Training directors feel the urgency to present cognition and accomplishments more quickly and expeditiously whenever and wheresoever needed. In the age of just-in-time production, just-in-time preparation becomes a critical component to organisational success ( Urdan & A ; Weggen 2000 ) .

Cost Savingss:

Strother mentioning Newton & A ; Doonga ( 2007 ) assesses the “ effectivity of e-learning in corporate preparation plans and gives some really impressive illustrations of i¬?nancial benei¬?ts of corporate e-learning. She quotes that IBM ‘s reported economy of $ 200 million in 1999 through transition of their preparation bringing methods to e-learning, Ernst and Young ‘s decrease of preparation costs by 35 % gained by replacing 80 % of schoolroom direction by utilizing e-training and Rockwell Collins decrease of developing outgo of 40 % by change overing 25 % of their traditional direction to e-training ” ( Newton & A ; Doonga, 2007 ) . Corporate e-learning besides saves on the traveling of the trainers which can be used as optimal usage of their skills.A

Accessibility & A ; Flexibility of bringing:

Schriver & A ; Giles 1999 prove that one of the benefits of e-learning us the handiness and flexibleness of bringing. It is cheaper to present the undertakings through decreased chance costs and decreased clip off from work. It besides helps to make the wider constituencies, besides to the most distant areas.

Globalization of concern is ensuing in multiplex challenges:

Progresss in information engineering and falling trade barriers facilitate concern around the Earth. As boundary lines become less meaningful, planetary competition intensifies. International enlargement has led to larger and more complex corporations. Today ‘s concerns have more locations in different clip zones and employ larger Numberss of workers with diverse cultural backgrounds and educational degrees than of all time. Therefore, more information has to be delivered in progressively larger organisations, disputing internal planning, logistics, and distribution. Corporations worldwide are now seeking more advanced and efficient ways to present developing to their geographically-dispersed work force ( Urdan & A ; Weggen 2000 ) .

Trainees learn at their ain gait:

The trainees can take their ain clip in understanding the construct and do n’t hold to hotfoot. E-learning besides helps them to hold the preparation stuff in their pant whenever required. Besides it can be referred whenever needed ( Elliot & A ; Clayton, 2007 ) .

Community edifice and Interactivity ( Handzic & A ; Ho-Hur, 2005 ) :

E-learning aid in community edifice and increases a batch of interactivity between the trainer and the trainee between different parts of the universe.

Beginning: Urdan & A ; Weggen ( 2000 )

The above pie chart shows the instruction and developing market in the US in the twelvemonth 2000.

A research was conducted in province of online acquisition in U.S. higher instruction. The survey was aimed at replying some of the cardinal inquiries about the nature and extent of on-line instruction based on responses from more than 2,500 colleges and universities. The below graph indicates the growing of pupils taking at least one on-line class.

Beginning: Allen & A ; Seaman ( 2007 )

Exhibit 4,5,6 & A ; 7 represent the per centum of replies the replies provided by the users in respects the statements on the advancement of e-learning in UK organisations..

Restrictions of e-learning:

“ E-learning restrictions can be categorized as technological restrictions, personal issues and design restrictions ” ( Wong, 2007 ) .

Technological restrictions:

Wong 2007 believes that for e-learning you need to hold a computing machine or a laptop to hold entree to e-learning. Rumble ( 2000 ) cited in Wong ( 2007 ) says that e-learning comes with benefits such as limitless entree 24 hours, 7 yearss a hebdomad, this privilege does non look to be executable for some people in rural countries due to the inability to entree Internet services. The Internet incursion rate in Malaysia is merely 31.8 % ( Phang, 2004 cited in Wong, 2007 ) . Good cyberspace velocities are the basic demand and these are merely available in few topographic points and non in all. Bose 2003 cited in Wong 2007 mentioned that, while it is executable to entree to high-speed bandwidth within the university campus, it becomes a job outside the campus, where Internet installations are less sophisticated.

Handzic & A ; Ho-hur ( 2007 ) say that a batch of research workers think that e-learning lead to feelings of isolation, defeat, anxiousness and confusion.

Personal issues ( Wong 2007 ) :

Lack of personal technological accomplishments can be an issue in e-learning. The new people coming and fall ining e-learning might experience clueless as they do n’t hold a instructor to steer them. A Elearners have to be techno understanding.

Hamid ( 2002 ) cited in Wong ( 2007 ) stated that proficient accomplishments could do defeat to e-learning pupils due to the unconventional e-learning environment and isolation from others. Dringus ( 200 ) cited in Macpherson et Al. ( 2004 ) agrees Hamid stating that e-learners may be unable to prolong their impulse unless they have right accomplishments and they are self motivated.

Design Restrictions:

Poor design of the e-learning courseware is a major issue for scholars and e-learning suppliers Ivergard & A ; Hunt ( 2005 ) cited in Wong ( 2007 ) . The design should be easy to understand so that the scholar has the motive to larn. Courseware design should be tailored to the demands of the scholars: it should be easy to utilize and pupils should hold easy entree to guidance and information ( Howell, Williams & A ; Lindsay 2003 ; James-Gordon, Young & A ; Bal, 2003 cited in Wong 2007 ) .

The undermentioned illustration explains how China adopted E-learning with the aid of 5 influential factors ( Duan et al. , 2010 ) .

A the above figure explain the structural theoretical account cardinal theoretical accounts explicating factors of e-learning.

A Another illustration of corporate e-learning is taken up by Japan. The Japan e-learning market reached 1350 billion hankerings in 2004, an addition of 41.3 % from 2003 ( Schnack, 2005 ) .

Traditional acquisition:

Traditional acquisition is sitting in the category physically and taking lessons. The traditional schoolroom puting adds value in footings of direction lucidity. Traditional acquisition is available about every portion of the universe where instruction is available. Students and the instructors are comfy with the schoolroom environment as they have been ever used to it. Teaching in this environment is more informal ( Chen & A ; Jones, 2007 ) . Traditional schoolroom learning gives an chance to the pupils to inquire self-generated inquiries in the category. The instructor can reply to the questions of the pupil ‘s right in the category. Traditional larning gives chance to pupils to interact with other pupils and have unrecorded treatments on subjects and have different sentiments on one construct. Interaction between pupils is an of import portion of single development. Teachers use state of affairss to explicate constructs to pupils which give them a pattern to believe on the topographic point and come up with solutions in a speedy clip ( Lunce, 2006 ) .

Surveies on e-learning have identified tonss of benefits like cost nest eggs, flexibleness and handiness of bringing and community edifice and interactivity ( Newton & A ; Doonga ) . Besides there is extended research on the restrictions of e-learning.

The biggest difference between the two acquisition is the bringing methods so it is really of import to make a proper research in this affair to happen the differences. Important end of this survey was to be able to do meaningful comparings between two bringing methods ( Chen & A ; Jones, 2007 ) .

Mind the spread

Surveies on e-learning have identified a batch of benefits and restrictions. There is non a batch of research done on the difference between traditional room larning andA e-learning. This research will give us an thought about what do people prefers? Though there are many benefits proven but it ‘s the people who will be utilizing e-learning in twenty-four hours to twenty-four hours life, so it is really of import to take their sentiment intoA consideration. In other words we will seek to happen the user friendly of e-learning in the sentiment of the people utilizing this. This research will besides give an thought to the people be aftering to take up e-learning in future. This research should be able to warrant the benefits and restrictions of e-learning in comparing to the traditional schoolroom acquisition.

Research inquiry: What do people prefer, e-learning or traditional schoolroom acquisition and why?

Research design

Methods, Methodology & A ; Data Collection:

Methods are the techniques that are used to roll up and analyze the information.

Methodology determines whether the execution of peculiar methods is successful or non ( Veal.

The method that can be used for this will be quantitative & A ; qualitative methods. The qualitative methods will assist garnering information in deepness and will be more subjective. The quantitative research will be more nonsubjective and will be analysed more statistically.

Qualitative methods

Samples / Focus groups:

Peoples from different administrations who use e-learning, a sample will be from administration which does non utilize e-learning, a group of pupils who use acquisition and the last group who does non. Concentrate groups can be made and asked about the benefits of e-learning and traditional acquisition. This argument will give a good cognition about the ideas of people about both the constructs. The findings from the focal point groups will assist us to fix the questionnaire for the in depth interviews.

Different questionnaires will be used for different groups. As the demographics of each group will be different the inquiries have to be prepared maintaining the intent of the research in head. Questions asked to the administrations utilizing e-learning will be largely based on the benefits, restrictions and the betterments to be made in e-learning, while on the other side the non user group will be educated first about e-learning and so asked whether they will be acute to travel to e-learning. The inquiries will be based on workplace e-learning. Same technique of two different questionnaire used for two groups will be used for the pupil groups but with different set of inquiries which will be more based on e-learning school instruction.

In-depth interviews:

The questionnaire made with the aid of the findings of the focal point groups will be explanatory. In-depth interviews will give an penetration of the thought of people sing these constructs. The in depth interviews inquiries will be connected to each other.

Surveies:

Surveies will be conducted in general to acquire statistics of the figure of people interested in e-learning or traditional acquisition. The questionnaire of the study will be a mix of unfastened ended and near complete inquiries. The inquiries in this study will be more general to acquire the Numberss merely, like how many people are interested in e-learning and how many in traditional schoolroom acquisition.

Datas Analysis:

Data Analysis will be divided into 3 different phases:

Data Decrease: The irrelevant informations will be discarded and merely the information which is necessary and related to the research subject will be kept.

Datas Display: The informations will be displayed with the aid of graphs and tabular arraies as ocular graphs can give a better apprehension of the informations.

Decision: The findings and the of import material of the research will be entered in the signifier of a study. These decisions are stored so that they be used for future researches every bit good.

Decision

As seen through the assorted diaries and beginnings related to e-learning, it is rather obvious that the narrative is instead double. There are surveies conducted to prove the worthiness of e-journal, whether people prefer to utilize this method, but as indicated earlier, there isn’t much research on comparing the traditional schoolroom method of learning with the alleged hereafter of learning – e-learning. Where corporate are required to supply cognition through interdisciplinary countries of the organisation, e-learning tends to be a cost-saving method of cognition scattering. Though this might be true, there are a batch of people who prefer human interaction, instead the traditional method of learning. Based on this, I decided that future research can be conducted to happen out what types of industries, entities or any such constitution, therefore an increased figure of studies throughout the workspace spectrum are highly of import to happen out the penchants of people in different parts of the Earth.
