The within-subjects ANOVA always has fewer degrees of freedom than the independent F because it takes into account the same subjects being measured multiple times, leading to a decrease in the overall variability of the data. This reduction in variability causes a decrease in degrees of freedom, making the within-subjects ANOVA have fewer degrees of freedom than the independent F.
