Wanted--Central Tendency and Variability of Test Norm Tables: How to Recover Them?

Peer reviewed

Krus, David J.; Liang, Kun-Hsia T. – Educational and Psychological Measurement, 1984

An algorithm for estimation of means and standard deviations or raw scores underlying table values of standard test scores is presented. An application of a computer program, operationalizing the suggested algorithm, is discussed within the framework of a comparison of estimated and known table values for sample Minnesota Multiphasic Personality…

Analysis of Covariance: A Proposed Algorithm.

Peer reviewed

Frigon, Jean-Yves; Laurencelle, Louis – Educational and Psychological Measurement, 1993

The statistical power of analysis of covariance (ANCOVA) and its advantages over simple analysis of variance are examined in some experimental situations, and an algorithm is proposed for its proper application. In nonrandomized experiments, an ANCOVA is generally not a good approach. (SLD)
