Quizplus · Accepted Answer

An experiment involves controlling one variable, called the independent variable, and observing and recording the results on the other variable, called the dependent variable. This allows the researcher to establish cause-and-effect relationships between the variables. Case studies and observations do not involve controlling variables in the same way, and social research is a broader term that can encompass many different methods, including experiments.
