Internal consistency on a test would be measured by _____.

Question

Quizplus · Accepted Answer

Internal consistency is the degree to which different items on the same test are measuring the same construct. One way to measure internal consistency is by using a split-half reliability measure. This involves dividing the test into two parts (e.g. odd-numbered items versus even-numbered items) and comparing the scores on the two halves to see how closely they match. By measuring the correlation between the two halves of the same test, we can determine the internal consistency of the test. Therefore, giving two halves (odd versus even items) of a test to the same sample and measuring the correlation between the scores is the best measure of internal consistency.
