Question

Quizplus · Accepted Answer

Random assignment of participants to different groups is a technique commonly used in experiments to ensure that each group is similar in composition, and any observed differences between groups can be attributed to the experimental manipulation rather than preexisting differences between participants. Surveys involve collecting data through self-report questionnaires, multiple cross-sectional studies involve comparing data from different groups at the same time point, and longitudinal studies follow the same group of participants over time.
