Detailed explanation-1: -Experimenters utilize variables to make comparisons between an experimental group and a control group. A variable is something that researchers can manipulate, measure, and control in an experiment.

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: -A control group is used as a comparison for the experimental group. The control group is the group in an experiment that does not receive any change in the variable. This group is left as natural as possible and used as a control to see if there is a change from the normal results.

Detailed explanation-4: -Controls or Controlled Variables A part of the experiment that is not being tested and is used for comparison of the experimental results. A control group should be used when conducting an experiment.

Detailed explanation-5: -It’s called “independent” because it’s not influenced by any other variables in the study.
