The Chief Reader's decision is based upon what percentage of students earned each AP Grade over the previous three years, how students did on multiple-choice questions that are used on the test from year to year, how he or she viewed the overall quality of the answers to the free response questions, how university students who took the exam as ...
Multiple choice questions lend themselves to the development of objective assessment items, but without author training, questions can be subjective in nature. Because this style of test does not require a teacher to interpret answers, test-takers are graded purely on their selections, creating a lower likelihood of teacher bias in the results. [8]
There are 40 multiple-choice questions per session. Several disciplines require a common morning breadth exam which broadly covers the discipline and then a more detailed afternoon depth exam where the test taker selects a more detailed area of the discipline. Other disciplines essentially have morning and afternoon breadth exams. [4]
For example, if a = 2 and p = 7, then 2 7 = 128, and 128 − 2 = 126 = 7 × 18 is an integer multiple of 7. If a is not divisible by p, that is, if a is coprime to p, then Fermat's little theorem is equivalent to the statement that a p − 1 − 1 is an integer multiple of p, or in symbols: [1] [2] ().
Classical test theory is an influential theory of test scores in the social sciences. In psychometrics, the theory has been superseded by the more sophisticated models in item response theory (IRT) and generalizability theory (G-theory).
A test score is a piece of information, usually a number, that conveys the performance of an examinee on a test. One formal definition is that it is "a summary of the evidence contained in an examinee's responses to the items of a test that are related to the construct or constructs being measured."
In psychometrics, item response theory (IRT, also known as latent trait theory, strong true score theory, or modern mental test theory) is a paradigm for the design, analysis, and scoring of tests, questionnaires, and similar instruments measuring abilities, attitudes, or other variables.
The General Aptitude Test Battery (GATB) is a work-related cognitive test developed by the U.S. Employment Service (USES), a division of the Department of Labor. It has been extensively used to study the relationship between cognitive abilities, primarily general intelligence, and job performance. [1] [2]
