Definitions:

Systematic Variance

Error Variance

Random variability in a set of scores that is not the result of the independent variable. Statistically, the variability of each score from its group mean.

Between-Groups Variance

captures the differences in means across different groups in an experiment, reflecting how much group members vary from each other overall.

Within-Group Variance

The variation of observations within a single group or category, measuring how much individual scores differ from the mean of that group.
