Intelligence Three Test Comparison
Society has been intrigued with the human mind since the beginning of time whether it deals with expanding the mind, strengthening, conditioning, or testing the limitations. A popular way to test the human mind is through the use of an intelligence test. In order to test the human mind on intelligence it must be defined to have reliable constructs that can be measured. Intelligence is being able to how well you learn from experiences and being able to adapt to the environment. Intelligence test the WISC uses four subtest groups to measure intelligence, which are verbal comprehension, perceptual reasoning, working memory, and processing speed.
These four subtest groups are constructs of intelligence broken into categories based on the skill type. Within the subtest these categories are used in intelligence test, for example the Shipley uses only vocabulary and abstraction as measurements of intelligence. IQ test vary with what types of constructs being used from using two items to all fifteen items. This paper is comparing the scores of three different IQ test, the Shipley, Wonderlic, and the classical IQ test. Similar to the comparing and contrasting of scores the ways each test defers will be examined along with the strength, purposes, and weaknesses of each test.
The first test the Shipley, which is an intelligence test that is measuring education and intellectual deterioration. The test is broken up into two parts first the vocabulary section where participants have ten minutes to answer forty vocab questions based on the similarity of the word compared to the four answer responses. The second part of this test was the abstraction part where twelve minutes was given to answer twenty-five questions. This particular test showed high internal consistency at . 92 along with acceptable test-retest scores at . 87-. 4, and a SEM at 4. 57, which is a medium SEM. The Validity for this test showed good concurrent validity. The standardization for the Shipley is a total of 2,826 with the demographic of 1,203 adults and 1,876 children. The downfall of the Shipley is that scores are highly depend on the verbal and abstraction ability not including any of the other constructs for testing intelligences. Thus this supports the issue of the Shipley being bias to people who have poor English skills or it is their second language making the test more challenging for them.
I felt that the score I received on the vocabulary portion was accurate in regards to vocabulary IQ because I do struggle with learning and comprehension, spelling, and vocabulary. I scored in the lower 21% ranking for vocabulary, which isn’t surprising because a large amount of words I didn’t understand and was guessing. The scores seemed to favor people with a wide comprehensive vocabulary and people who are native English language speakers. What doesn’t seem fair is for the people who struggle with aspects such as vocab are going to have low scores, which can hinder aspects where the scores of the Shipley are used as a deciding factor.
Although overall the abstract portion balanced out the combined score leaving me at a average percentile ranking for the Shipley. Some sources of error that my affect the results of the test could be the time of day the test was taken, if each test was instructed in the same manner along with the other previously discussed examples. The Wonderlic intelligence test is more widely used in the work force and is used to evaluate and aid in hiring decisions. It intends to measure the general intelligence of adults in the business and industry field.
The test consists of fifty questions that progressively get harder as they go on. The time limit is twelve minutes to complete as many correct answers as possible. The test was not intended for people to complete in the elapse time. The internal consistency, test re-tests, and concurrent validity are all excellent for this test. This suggest that this test is reliable and measures what it intendeds to measure. The SEM is much smaller than the Shipley at 1. 4. While having excellent standardization with a sample size was 100,000 individuals.
This test has been known as or called unfair, because for ESL individuals have a much harder time with the vocab and comprehension part. It could take them longer to read or understand certain aspects, which could slow them down and affect their scores for the test that could potentially decide who gets the job based on scores. The tests are scored and compare the standard score with the corresponding grade level. Age is also a factor in this test to where the older you are the higher number of points you can add to your final score.
On this test I strongly agree with the idea that this test is unfair because of the short time limit you are given to take the full test. Also the content on the test may be examining your intellectual abilities but may not relate to the on the job aspect of learning or type of work duties. This is starting people off who need accommodations such as longer test taking, anxiety, ESL individuals, and people struggle in school to perform lower than people who don’t need these accommodations. It has been proven that certain ethnicity do better or worse on this test.
So that alone is giving an advantage to a particular group because a portion of people start out with a disadvantage based on socioeconomic status, education, ethnicity, and parents education level. A source of error that can occur with this test could be the amount of time given to participants, time of day or beginning or ending of a school week and possibly ethnicity based on previous scores. The online intelligence test is used as a predictor of your academic achievements. It is measuring general intelligence; this test used several of the subtests that were previously discussed.
The scoring was scaled by the ability to retain previous learned knowledge. The knowledge being tested was acquired through education and experience. What I learned about intelligence assessment was that there are many types of intelligence test and they each vary in aspects of testing. What I learned about my own intelligence was simply confirmed with the three test results. Prior to the intelligence test I would have guested that my levels of intelligence was around average. Overall for all three test a consistent finding of an average IQ score was found after reviewing the results.
For the first Shipley my standard score was right on the 100 mark that coordinates to the fifty percentile of the overall scores of the Shipley. This is right on the average of overall scores for the Shipley. The Wonderlic showed similar results where I answered twenty-eight items scoring fifteen items correct out of fifty total items. The scoring was comparing your total score to the years of education completed. I scored in the tenth grade category with the cumulative ranking of 18. 72 when compared to adults and a 2. when compared to college graduates. When looking at the level of education completed the score puts me at grade level ten, which is right in the middle of the years of education. The interpreting of the WPT test results state that I may enter high school and will probably select classes that are on a less academic track. This is the lowest amount of educational success that is interpreted and I am on my way to achieving the highest level of interpretation being a college graduate. This test doesn’t seem to be an accurate predication of education levels.
Although my scores fall below the mean on this test it is fairly close to the overall mean. For the final online IQ test found that I was right around the overall mean again with my percentile ranking at 45% which is very close to the middle. Moreover I have confirmed through the three IQ test that I rank in the overall average category. When comparing the IQ results to my class performance or GPA they do correlate. My cumulative GPA is 2. 5 which is right on the average for overall GPA, which relate to the three scores I received from the test confirming an average overall IQ and learning processing.
With my GPA and the overall IQ test scores correlating can suggest that the IQ test are a good predictor or accurate predictor of GPA. Also can imply that GPA is a predictor of your overall intelligence. Looking at my overall data suggest that I am of average intelligence with strongly correlates with my GPA. I agree with the findings of average IQ score because it reflects my grades in school throughout high school and college and attitude about my cognitive functioning. Although I disagree that the test should be used as a predictor or and outcome variable for selection decisions.
