Quizplus · Accepted Answer

The use of random assignment defines true experimental research.
Random assignment refers to the way in which participants are assigned to different levels of independent variables. Random selection refers to the way in which participants are selected from the population. Sample size and double-blind settings have nothing to do with the true or quasi-experimental research.
