Peer reviewedHakstian, A. Ralph; And Others – Psychometrika, 1989
Four measurement designs are presented for use with correlation coefficients corrected, in one variable, for attenuation due to unreliability (partially disattenuated). Associated asymptotic variance/covariance expressions are presented. Empirical simulation results illustrate the satisfactory Type I error control and statistical power of the…

Peer reviewedReynolds, Sharon B.; And Others – Computers and Education, 1991
Discussion of knowledge maps focuses on a study at Texas Christian University that was conducted to determine the effects of scripted cooperation in a hypermap environment. Hypermap and hypertext versions of MacStat--the software for univariate statistics that was used in the study--are described, and performance measures are explained. (17…
