The difference between repeated measurements to establish test-retest reliability and experiments using repeated measures designs is that in experiments with repeated measures designs

B)measurements are compared for different conditions of an independent variable.
C)measurements occur only twice.
D)a correlation coefficient would be used to determine consistency across measurements.

Question

Quizplus · Accepted Answer

In experiments with repeated measures designs, measurements are taken for the same participants across different conditions of an independent variable. Therefore, the focus is on comparing measurements across different conditions to evaluate the effect of the independent variable on the dependent variable. Test-retest reliability is not the primary concern in this type of design, although it may be assessed as a secondary measure. Option A and C are incorrect because the reliability of measurement is always important, and measurements occur more than twice in an experiment using a repeated measures design. Option D is incorrect because correlation coefficients are used to assess the strength and direction of the relationship between two variables, not the consistency of measurements.
