Question

Quizplus · Accepted Answer

This design involves randomly assigning participants to different conditions (in this case, different walking schedules) and comparing the outcomes between the groups. This is different than a within-subjects design, where participants serve as their own controls and are exposed to all conditions. The other choices, matched groups and multiple independent groups, do not accurately describe the design in this study.
