Experimental Research Questions Medium
The role of control groups in experimental research is to serve as a baseline or comparison group against which the experimental group is measured. Control groups are essential in order to determine the true effect of the independent variable being studied. By keeping all variables constant except for the independent variable, researchers can isolate and measure the impact of the independent variable on the dependent variable. The control group provides a reference point to compare the experimental group's results, allowing researchers to determine whether any observed changes are due to the independent variable or other factors. Control groups help ensure the validity and reliability of experimental research by minimizing confounding variables and providing a standard for comparison.
