An analysis of variance produces SS_total = 80 and SS_within = 30.For this analysis,what is SS_between? A)30 B)50 C)110 D)Cannot be determined without additional information

Question

Quizplus · Accepted Answer

The formula for total sum of squares is SSS = SSW + SSB, where SSW represents the within-group sum of squares and SSB represents the between-group sum of squares. 
SSB = SSS - SSW 
Given SSS = 80 and SSW = 30, 
SSB = 80 - 30 = 50. Thus, the answer is B.

An Analysis of Variance Produces SStotal = 80 and SSwithin
