Assume that a new high school science aptitude test is being developed, and in the course of that development several procedures and techniques have been used to provide evidence for its validity. These procedures are listed in the following statements. For each statement, decide which type of evidence in Figure 3.2 is directly addressed. Explain why you made the choice you did.
a. For a sample of 150 students in Grade 10, scores on the odd-numbered items were correlated with scores on the even-numbered items.
b. Scores from 300 first-year students obtained from a September administration of the test were correlated with scores of the same group obtained from a February administration.
c. Scores of 200 first-year students obtained from a September administration of the test were correlated with the general science course grades of these same students obtained from school records in January.
d. Scores of students who had taken one, two, three, and four science courses were compared to see if they differed on average.
e. A section of the test manual describes seven aspects of science aptitude and the number of items measuring each aspect.
