Split-half coefficient
Websplit-half correlation . This involves splitting the items into two sets, such as the first and second halves of the items or the even- and odd-numbered items. Then a score is computed for each set of items, and the relationship between the two sets of scores is examined. Web9 Aug 2024 · Split Half Reliability is an internal consistency approach to quantifying the reliability of a test, in the paradigm of classical test theory . The name comes from a simple description of the method: we split the test into two halves, calculate the score on each half for each examinee, then correlate those two columns of numbers.

WebL 4 is, in fact, the Guttman split-half coefficient. Moreover, it is a lower bound for the true reliability for any split of the test. Therefore, Guttman suggests finding the split that maximizes L 4, comparing it to the other lower bounds, and choosing the largest.
