EVERYDAY SCIENCE

Detailed explanation-1: -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.

Detailed explanation-2: -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.

Detailed explanation-3: -The purpose of a control group in an experiment is to increase the validity of the experimental results by having something to compare, the experimental variables to.

Detailed explanation-4: -The control group (sometimes called a comparison group) is used in an experiment as a way to ensure that your experiment actually works. It’s a way to make sure that the treatment you are giving is causing the experimental results, and not something outside the experiment.

Detailed explanation-5: -A typical use of a control group is in an experiment in which the effect of a treatment is unknown and comparisons between the control group and the experimental group are used to measure the effect of the treatment.
