The Effect of Violating the Assumption of Equal Item Means in Estimating the Livingston Coefficient.
Lovett, Hubert T.
Educational and Psychological Measurement, v38 n2 p239-51 Sum 1978, 78
The validity of five methods of estimating the reliability of criterion-referenced tests was evaluated across nine conditions of variability among item means. The results were analyzed by analysis of variance, the Newman-Keuls test, and a nonparametric procedure. There was a tendency for all of the methods to be conservative. (Author/JKS)
