Why is a control group important in experimental research?
A control group in an experiment does not receive the treatment. Instead, it serves as a comparison group for the treatments. Researchers compare the results of a treatment group to the control group to determine the effect size, also known as the treatment effect.
A control group is typically thought of as the baseline in an experiment. In an experiment, clinical trial, or other sort of controlled study, there are at least two groups whose results are compared against each other.

Feb 7, 2023 · A control group is a common tool that researchers use. It allows them to prove a cause-and-effect relationship with an independent variable. This variable does not change for the control group. In this sense, the control group is the status quo. Researchers compare the effects in the experimental group against the control group.
Researchers use placebos in the control group to determine if any differences between groups are due to the active medicine or the participants' perceptions (the placebo effect). Control Group. A level of the explanatory variable that does not receive an active treatment; they may receive no treatment or a placebo. Placebo Group.
Jan 29, 2020 · A control group in a scientific experiment is a group separated from the rest of the experiment, where the independent variable being tested cannot influence the results. This isolates the independent variable 's effects on the experiment and can help rule out alternative explanations of the experimental results.
