Quizplus · Accepted Answer

Random assignment is a key feature of experimental research, which involves manipulating an independent variable and randomly assigning participants to different conditions to test for causal effects. Observational research, on the other hand, involves observing and measuring variables without manipulating them, and therefore cannot use random assignment. Therefore, the correct answer is choice A, as random assignment is only feasible when using an experimental strategy.
