Quizplus · Accepted Answer

From the ANOVA table, we can see that the number of treatments is equal to the number of treatment groups minus 1. In this case, the number of treatment groups is 3 (from the "df" column of the "Treatments" row), so the number of treatments is 3 - 1 = 2. Therefore, the best choice is C.
