Nicole Asked Her Research Lab Partner Why Their Repeated-Measures Design

Nicole asked her research lab partner why their repeated-measures design was classified as a within-subjects design. Nicole's research lab partner noted that participants in their repeated-measures design:

A) are measured twice, once at the beginning of the study and again at the end of the study.
B) are repeatedly measured on the dependent variable over time.
C) are measured on the dependent variable after exposure to each level of the independent variable.
D) are needed for adequate statistical power only because there are 15 participants.
