Quizplus · Accepted Answer

Random assignment is the process of assigning participants to experimental conditions in a way that every participant has an equal chance of being in any condition. This helps to minimize the effects of extraneous variables and increases the chances of making valid causal inferences about the effects of the independent variable on the dependent variable. Experimental control refers to the ability to manipulate and control the variables in an experiment. Quasi-experimental design refers to a type of research design that lacks random assignment, whereas random sampling refers to the process of randomly selecting participants from a population to be included in a study.
