Two New Formulas for F in Analysis of Covariance for Two Groups and One Covariable [electronic resource] / Thomas R. Knapp and William D. Schafer.

Two theorems concerning F in analysis of covariance with two groups (experimental and control) and one covariable (pretest score) are presented. The first shows explicitly that F is a direct function of the ratio of the variance about the regression line for the total sample to the variance about th...
