Question

Quizplus · Accepted Answer

If Jessica's test items are measuring more than one concept, it means that the questions in the test are not consistently measuring the same thing. This is a problem of internal consistency, which refers to the extent to which different items in a test or survey measure the same construct or idea. If the test has poor internal consistency, it means that the results may not accurately reflect the personality traits or achievement motivation of the eighth-graders being studied.
