Peer reviewedShontz, Franklin C. – Journal of Counseling Psychology, 1972
The approach to outcome research described here has the double merit of preserving individuality and permitting pooling of data for overall analysis of results. (Author)

Sirotnik, Ken – J Educ Meas, 1970
The assumption that an examinee's response to an item is independent of the context in which it occurs is tested. (PR)

Pedersen, Frank A.; Bell, Richard Q. – Develop Psychol, 1970
Despite the precautions in subject selection many of the usual sex differences appeared, including boys' higher level of aggression toward peers. (MH)

Gumm, George; Chambers, Gurney – Phi Delta Kappan, 1970
A previous article, EA 500 335, is criticized for claiming the applicability of the CRAM model without research documentation. (MF)

Krejcie, Robert V.; Morgan, Daryle W. – Educ Psychol Meas, 1970
A formula for determining sample size, which originally appeared in 1960, has lacked a table for easy reference. This article supplies a graph of the function and a table of values which permits easy determination of the size of sample needed to be representative of a given population. (DG)

Peer reviewedMayer, John D. – Perceptual and Motor Skills, 1983
Kelly's formula estimates sampling variance of correlation corrected for attenuation by using split-half reliabilities. In some cases, coefficient alpha estimate of reliability is preferable. A simulation study suggests a variation of Kelly's formula can be used appropriately with coefficient alpha. Kelly's formula is modified to accept…

Peer reviewedSmith, Philip L. – Educational and Psychological Measurement, 1982
Monte Carlo methods are used to explore the accuracy of a method for establishing confidence intervals for variance component estimates in generalizability studies. Previous research has shown that variance component estimation errors due to sampling are often larger than suspected. (Author/CM)
