In a repeated-measures ANOVA, the notation F(df_between, df_within) is used. The first number after F (in this case, 3) represents the degrees of freedom between groups, which is calculated as the number of treatments minus 1. Therefore, if df_between is 3, there were 4 treatments compared (3 + 1 = 4).
