Two-Way ANOVA

Main Effect

The effect of a single independent variable in ANOVA.

Interaction

In ANOVA, when the effects of one independent variable depends on the level of another independent variable.

Sum of Squares Total (SST)

In two-way ANOVA, it is given by SST = SSG₁ + SSG2 + SSG1 + SSE, where SSG1 is the sum of squares between groups in the first variable, SSG2 is the sum of squares between groups in the second variable, and SSG, is the sum of squares in the interaction between the two variables.

MSG1

Mean Square of the first categorical variable

MSG2

Mean Square of the second categorical variable

MSE

Mean Squared Error

Tukey HSD

Tukey Honest Significant Difference test - one way to check which differences between means are significant.

Bonferroni Correction

A correction method used to address the multiple comparisons problem - one way to check which differences between means are significant.
