What Control group is
A control group is a group in an experiment that does not receive the same treatment as the experimental group. It is used as a baseline for comparison to measure the effectiveness of the treatment.
Steps for a Control Group:
-
Identify the research question.
-
Define the experimental and control groups.
-
Administer the treatment to the experimental group.
-
Do not administer the treatment to the control group.
-
Monitor the results of both groups.
-
Compare the results of the experimental and control groups.
-
Draw conclusions from the results.
Examples
-
A control group is a set of subjects or participants in an experiment or study who do not receive the treatment or intervention being tested and instead receive either a standard treatment, a placebo, or no treatment at all.
-
In a randomized controlled trial, a control group is used to compare the results of the experimental group, as the results of the control group provide a baseline for comparison.
-
A control group can also be used to test the validity of an experiment by comparing the results of the experimental group to the results of the control group.
