In a one-factor between-subjects analysis of variance, if the independent variable has an effect, then the variability between groups (MSA) should be larger than the variability within groups (MSError). This is because MSA measures the differences between the sample means of each group, while MSError measures the differences within each group. Therefore, if the independent variable has a significant effect on the dependent variable, the differences between the groups should be greater than the differences within the groups, resulting in a larger MSA.
