(1) A.Treatments
Treatment. In an experiment, the factor (also called an independent variable) is an explanatory variable manipulated by the experimenter. Each factor has two or more levels, i.e., different values of the factor. Combinations of factor levels are calledtreatments.
(2)k-1
if there are k gropus then df of between groups SS will be k-1. if there are 6 groups and each group has 5 measurement then df of between groups SS=6-1=5
