Definition
A control group is a set of participants in an experiment that does not receive the treatment or intervention being tested, serving as a baseline to compare the effects of the treatment on the experimental group. This helps researchers isolate the impact of the independent variable on the dependent variable.
Summary
A control group is a fundamental concept in experimental research, serving as a baseline to compare the effects of a treatment. By not receiving the treatment, the control group allows researchers to determine whether changes in the experimental group are due to the treatment or other factors. Understanding the role of control groups is essential for conducting valid experiments and drawing accurate conclusions. In addition to control groups, researchers must also consider variables, randomization, and data analysis. These elements work together to ensure that experiments are designed effectively, leading to reliable results. Mastering these concepts is crucial for anyone interested in scientific research and experimentation.
