This scenario exemplifies a longitudinal design because the same group of participants is being followed over time and data is being collected at multiple points in time. Sampling design involves selecting a representative group from a larger population, experimental design involves manipulating variables to observe their effect on an outcome, and double-blind experiment involves neither the participants nor the researchers knowing which group is receiving the treatment or placebo.
