www.lexjansen.comSSE for the repeated measures ANOVA is 6.833+5.333=12.167 based on 6+6=12 degrees of freedom. Similarly, the SS(Patient) can added to obtain the SS(Patient(Vaccine)) for the repeated measures ANOVA, 11.667+13.667=25.333 with 3+3=6 degrees of freedom. Notice that the sums of squares for the time effect (SS(Visit)) are not additive. Solution

Statistics: Analysing repeated measures data
statstutordevelopment.lboro.ac.ukIn this case you would probably use repeated measures ANOVA (or, if the assumptions for this are not met, the non-parametric equivalent, Friedmans’s test). 3.2 Two or more groups of subjects The temptation with such data may be to compare subjects at each time point separately, perhaps with a series of unpaired t-tests. This is not appropriate.

Repeated measures (within-subjects) ANOVA
www.sheffield.ac.ukRepeated measures ANOVA analyses (1) changes in mean score over 3 or more time points or (2) differences in mean score under 3 or more conditions. This is the equivalent of a one-way ANOVA but for repeated samples and is an extension of a paired-samples t-test. Repeated measures ANOVA is also known as ‘within-subjects’ ANOVA.
