What distinguishes true experimental research from quasi-experimental research?

Sample size
Random selection
Random assignment
Double-blind setting

Explanation

Answer: C - 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.
