True Scores John took two separate and completely different tests. How many “true scores” does he have? Why? The definition of the true score states that each examinee has one true score value, which is the average observed score the examinee would earn over many repeated tastings. For each situation, indicate the type of reliability estimate that would be most appropriate. A classroom teacher wishes to check on the reliability of a multiple-choice final examination in biology. A counseling psychologist wishes to develop two attitude inventories, one to be used as a pretest and one as a post-test, for a drug education program (that lasts only one day).
A nationally used college admissions examination is given in fall and spring, with a different form used on the two occasions. College admission directors want evidence that it does not matter when an applicant takes the test. Item 3 (p. 155) provides a table that contains descriptive data on two hypothetical subtests of a standardized achievement battery, which has two alternate forms. Use the data to answer the question. What are the standard errors of measurement for the two forms of these tests? Is it always best to use the test form with the smallest standard error of measurement? Why?
