Question

In a repeated measures ANOVA, the total sum of squares can be partitioned into three sources of variation. What are those three sources of variation? For each source of variation, describe whether that source represents a type of between-groups variation or within-groups variation.,

Answer 1

(a)

The 3 sources of variation are:

(i) SSconditions = Conditions Variability

(ii) SSsubjects = Subject Variability

(iii) SSerror = Error Variability

(b)

SSconditions = Conditions Variability represents a type of between-groups variation

SSsubjects = Subject Variability and SSerror = Error Variability represent a type of within-groups variation
