Quantitative Methods Questions
A control group in experimental research refers to a group of participants who are not exposed to the independent variable or treatment being studied. The purpose of having a control group is to provide a baseline for comparison, allowing researchers to determine the effects of the independent variable by comparing it to the control group's outcomes. The control group helps to isolate and identify the specific impact of the independent variable on the dependent variable, thus enhancing the validity and reliability of the research findings.
