Describe random selection and random assignment.
What will be an ideal response?
Ans: Answer would ideally include: Random selection is the process of choosing, in random fashion, individuals for participation in a research study, such that every member of the population has an equal chance of being selected to be a member of the sample. Random assignment means that every individual who has been randomly selected to participate in the experiment has an equal chance of being assigned to any of the groups (i.e., experimental or comparison groups) being compared in the study. Both random selection and assignment help ensure equivalence of groups, and control for many extraneous variables that might otherwise contaminate the results of the research study.
