Jul 3, 2020 · In a scientific study, a control group is used to establish causality by isolating the effect of an independent variable. Here, researchers change the independent variable in the treatment group and keep it constant in the control group. Then they compare the results of these groups.

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.
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.
control group, the standard to which comparisons are made in an experiment. Many experiments are designed to include a control group and one or more experimental groups; in fact, some scholars reserve the term experiment for study designs that include a control 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.

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.
