Question

Quizplus · Accepted Answer

Split-half reliability refers to a method of measuring a test's internal consistency by separating the test into two halves and correlating the scores of the two halves. In this case, the researchers correlated subsets of items within the same subtest of the K•ABC, which is an example of split-half reliability.
