Question

Quizplus · Accepted Answer

The variation between the groups reflects the effect of the factor levels, as it examines the differences between the mean values of the dependent variable across the different levels of the factor. The variation within the groups, on the other hand, reflects the variability of individual scores within each group. The error mean square represents the unexplained variation in the dependent variable that cannot be attributed to the factor or other sources of variation. Sampling error refers to the natural variability that occurs when taking a sample from a larger population. The interaction effect refers to the effect of the combination of different levels of two or more factors on the dependent variable.
