In experiments with repeated measures designs, measurements are compared for different conditions of an independent variable. This is different from using repeated measurements to establish test-retest reliability, which focuses on the consistency of the measurements over time. In experiments with repeated measures designs, the focus is on comparing the same participants under different conditions, rather than comparing the same measurement taken at different times. The reliability of measurement is still important, but it is not the primary concern in this type of design. Instead, the focus is on how the independent variable affects the dependent variable within the same individuals. Correlation coefficients may be used to assess the consistency of measurements, but this is not unique to experiments with repeated measures designs.
