Which one of the following methods of estimating reliability/precision requires dividing the test into halves and then correlating the set of individual test scores on the first half with the set of individual test scores on the second half?

B) coefficient alpha
C) split-half method
D) correlation method

The split-half method involves dividing the test into two halves and correlating the set of scores from one half with the set of scores from the other half to estimate reliability/precision. The test-retest method involves administering the same test to the same group of participants on two different occasions and correlating the scores from both occasions. Coefficient alpha (also known as Cronbach's alpha) is a measure of internal consistency reliability that assesses how well the items on a test measure the same construct. The correlation method is too broad of a term without further explanation.
