Quizplus · Accepted Answer

SSA, or sum of squares between groups, represents the variation of group means from the grand mean. It measures the degree of variability among the treatment groups and is commonly used in hypothesis testing to determine whether there are significant differences between group means. Therefore, option B is the correct choice. Options A, C, and D are not accurate because they refer to different sources of variation that are not represented by SSA.
