The test is long and seems to cover the content thoroughly. Carlos divides the test in two and assesses the reliability of the entire test and the reliability of the two halves. Carlos is assessing the ________________ of the test.
A) content validity
B) internal consistency reliability.

Question

Quizplus · Accepted Answer

Carlos is assessing the internal consistency reliability of the test by splitting it into two halves and measuring the consistency of scores between the two halves. Content validity would involve ensuring that the test covers the relevant content, test-retest reliability would involve administering the same test to the same group of students at different times to assess consistency, and criterion-related validity would involve comparing scores on the test to some external criterion or measure of achievement.
