The degrees of freedom between treatments (df_between) is calculated as the product of the degrees of freedom for each factor. For factor A with 2 levels, df_A = 2 - 1 = 1. For factor B with 3 levels, df_B = 3 - 1 = 2. The interaction df is df_A * df_B = 1 * 2 = 2. Therefore, df_between = df_A + df_B + df_interaction = 1 + 2 + 2 = 5.
