DEVELOPMENT OF SOFTWARE FOR ANOVA THAT CAN GENERATE EXPRESSIONS OF VARIANCE EXPECTATIONS

In recent years, a large number of programs have been equipped with ANOVA (Analysis of Variance) functions. The expression of expectation of variance in ANOVA must be calculated in order to evaluate each standard uncertainty. However, modern software does not yet offer the functionality to calculate this expression of expectation of variance. In this study expectations of variance in ANOVA were formulated and a new program that calculates the expression of the expectation of variance in typical and specific experimental designs and displays symbolic expectations of each variance was developed.
