The benefits of the within-groups design are seen in the calculation of the F statistic, in that the:
A) numerator is larger, resulting in a larger F statistic.
B) numerator is smaller, resulting in a smaller F statistic.
C) denominator is smaller, resulting in a larger F statistic.
D) denominator is larger, resulting in a smaller F statistic.

The within-groups design, also known as the repeated measures design, typically results in a smaller denominator in the calculation of the F statistic because it accounts for variability due to individual differences among participants, thus often leading to a larger F statistic. This is because the within-groups design controls for more sources of variance compared to between-groups designs.
