Quizplus · Accepted Answer

Random assignment is a process used in experimental designs to allocate participants to different groups using randomization. This ensures that each participant has an equal chance of being assigned to any group, which helps to control for confounding variables and allows for the comparison of treatment effects. This is a key feature that distinguishes true experiments from other types of research designs. Choices A, B, and D describe different concepts: random sampling (A), stratification or matching (B), and non-random sampling (D), none of which equate to or ensure random assignment.
