Since each … WebIn the simple, univariate split-plot approach to repeated measures data, the covariance structure among the observations within a main plot is used to adjust the degree of freedoms in the ANOVA to give approximate tests. The approximate ANOVA for a repeated measures CRD is shown below. 12.9.1 Repeated measures ANOVA

WebRepeated measures anova assumes that the within-subject covariance structure has compound symmetry. There is a single variance (σ 2) for all 3 of the time points and there is a single covariance (σ 1 ) for each of the pairs of trials. This is illustrated below. Stata calls this covariance structure exchangeable.
WebIf you are looking repeated measures, you are looking a paired t-test case.
