Real Statistics Support for Two Factor Anova. Similarly, as can be seen in Unbalanced Factorial ANOVA, when the input data is in Excel format the Two Factor Anova data analysis tool will automatically convert the data into standard format when the Regression analysis option is chosen. Two-Factor ANOVA, also known as factorial analysis, is an extension to the one-way analysis of variance. In a two-factor analysis, there are two variables, rather than one as in a single factor analysis. The assumption is that both variables, or factors, affect the dependent variable. Each factor contains two or more classes and the degree of. Analysis of variance or ANOVA can be used to compare the means between two or more groups of values.

Two-way ANOVA divides the total variability among values into four components. Prism tabulates the percentage of the variability due to interaction between the row and column factor, the percentage due to the row factor, and the percentage due to the column factor. The remainder of the variation is among replicates also called residual variation. One-Way vs Two-Way ANOVA: Differences, Assumptions and Hypotheses.
