D)in degrees of freedom

Question

Quizplus · Accepted Answer

SSTotal (or the total sum of squares) represents the overall variation in the data set, which is calculated as the sum of squared deviations between each individual score and the grand mean. Therefore, option A ("of the individual scores from the grand mean") is the correct answer. Option B ("of group means from the grand mean") refers to the between-groups sum of squares (SSBetween), while option C ("of scores within the treatment groups") refers to the within-groups sum of squares (SSWithin). Option D ("in degrees of freedom") is not relevant to the definition of SSTotal.
