Outliers are simply single data points within your data that. With such designs the repeated-measure factor the qualitative independent variable is the within-subjects factor while the dependent quantitative variable on which each participant is measured is the dependent variable.

A repeated measures one-way ANOVA is used to determine whether or not there is a statistically significant difference between the means of three or more groups in which the same subjects show up in each group. The table shows the p p -value associated with our F F -value. This is the equivalent of a one-way ANOVA but for repeated samples and is an extension of a paired-samples t-test.
