You are reading about reliability of a test in the test manual and notice that the researchers report using a Spearman-Brown coefficient.You can infer that internal consistency reliability was measured using:
A)the Kuder-Richardson formulas
B)coefficient alpha
C)split-half reliability
D)test-retest

Question

Quizplus · Accepted Answer

The Spearman-Brown coefficient is commonly used to adjust the reliability estimate when a test is split into halves to measure its internal consistency, which directly relates to option C, split-half reliability. This method involves dividing the test into two parts, administering it once, and then correlating the scores from the two halves. The Spearman-Brown coefficient is then used to predict the reliability of the full test based on this split-half reliability.
