Evaluating the Impact of Guessing and Its Interactions with Other Test Characteristics on Confidence Interval Procedures for Coefficient Alpha
Peer reviewed Peer reviewed
Direct linkDirect link
Paek, Insu – Educational and Psychological Measurement, 2016
The effect of guessing on the point estimate of coefficient alpha has been studied in the literature, but the impact of guessing and its interactions with other test characteristics on the interval estimators for coefficient alpha has not been fully investigated. This study examined the impact of guessing and its interactions with other test…

The Use of Moment Estimators for Mixtures of Two Binomials with One Known Success Parameter.
Peer reviewed Peer reviewed
Van Der Linden, Wim J. – Educational and Psychological Measurement, 1983
This paper focuses on mixtures of two binomials with one known success parameter. It is shown how moment estimators can be obtained for the remaining unknown parameters of such mixtures, and results are presented from a Monte Carlo study carried out to explore the statistical properties of these estimators.

Determining the Length of Multiple Choice Criterion-Referenced Tests When an Answer-Until-Correct Scoring Procedure Is Used.
Peer reviewed Peer reviewed
Wilcox, Rand R. – Educational and Psychological Measurement, 1982
When determining criterion-referenced test length, problems of guessing are shown to be more serious than expected. A new method of scoring is presented that corrects for guessing without assuming that guessing is random. Empirical investigations of the procedure are examined. Test length can be substantially reduced. (Author/CM)
