In a repeated-measures ANOVA, the degrees of freedom for the within-subjects factor is calculated as df = N - 1, where N is the number of subjects. The given degrees of freedom for the within-subjects factor is 24, which means N - 1 = 24, so N = 25. However, because it's a repeated-measures design, the total number of individuals is the same as the number of subjects, which is 25. The confusion might arise from interpreting the degrees of freedom, but the key is recognizing that the total number of participants is directly related to the degrees of freedom for the within-subjects factor in a repeated-measures ANOVA.
