Variance reduction analysis is a simple method for determining the effect of inequality of cell size on analysis of variance calculations. The suggested procedure has three steps. (Author/CK)

This memorandum is the manual for the VARAN (VARiance ANalysis) program, which is the latest addition to a series of computer programs for multivariate analysis of variance. As with earlier programs, analysis of variance, univariate and multivariate, is the main target of the program. Correlation analysis of all types is available with printout in…

The technique of analysis of covariance is examined for its relevance to educational and psychological investigations. A study of the arithmetic procedures, history, and statistical properties shows that, though the concepts are relevant to many data collection designs, the customary calculations are often inappropriate. Some suggestions are made…

The VARAN (variance Analysis) program is an addition to a series of computer programs for multivariate analysis of variance. The development of VARAN exploits the full linear model. Analysis of variance, univariate and multivariate, is the program's main target. Correlation analysis of all types is available with printout in the vernacular of…
