A K-Sample Significance Test for Independent Alpha Coefficients
Peer reviewed Peer reviewed
Hakstian, A. Ralph; Whalen, Thomas E. – Psychometrika, 1976
Details of a reasonably precise normalization technique for coefficient alpha are outlined, along with methods for estimating the variance of the normalized statistic. These procedures lead to the K-sample significance test. (RC)

A Comparison of Several Methods of Assessing Partial Knowledge in Multiple Choice Tests: I. Scoring Procedures
Peer reviewed Peer reviewed
Kansup, Wanlop; Hakstian, A. Ralph – Journal of Educational Measurement, 1975
Effects of logically weighting incorrect item options in conventional tests and different scoring functions with confidence tests on reliability and validity were examined. Ninth graders took conventionally administered Verbal and Mathematical Reasoning tests, scored conventionally and by a procedure assigning degree-of-correctness weights to…

A Comparison of Several Methods of Assessing Partial Knowledge in Multiple Choice Tests: II. Testing Procedures
Peer reviewed Peer reviewed
Hakstian, A. Ralph; Kansup, Wanlop – Journal of Educational Measurement, 1975
A comparison of reliability and validity was made for three testing procedures: 1) responding conventionally to Verbal Ability and Mathematical Reasoning tests; 2) using a confidence weighting response procedure with the same tests; and 3) using the elimination response method. The experimental testing procedures were not psychometrically superior…
