CONTROL GROUP Meaning and
Definition
-
A control group, in the context of scientific research, refers to a group or set of individuals who do not receive the experimental treatment or intervention under investigation. It serves as a baseline or comparison group against which the experimental group is measured. The primary purpose of including a control group is to establish a point of reference for evaluating the effects and outcomes of the intervention being studied.
Members of the control group are carefully selected to closely resemble the experimental group in terms of relevant characteristics such as age, gender, health status, or any other factors that may influence the outcome being assessed. However, unlike the experimental group, the control group does not receive the treatment or intervention being investigated.
By comparing the results obtained from the control group with those from the experimental group, researchers can discern whether any observed changes in the experimental group can be attributed to the intervention being examined. The control group provides a reference point that assists researchers in determining the effectiveness or impact of the treatment or intervention being tested. Additionally, it helps in minimizing the influence of confounding variables, thus enhancing the validity of the research findings.
In summary, a control group is a crucial component of scientific experiments, allowing researchers to make meaningful comparisons between the effects of a specific intervention and the absence of that intervention.

Etymology of CONTROL GROUP
The word "control" in the phrase "control group" is derived from the Latin word "contrarotulus", which means a counter-roll or duplicate register. In the 16th century, the term "control" was used to refer to a duplicate register used in accounting to check the accuracy of entries. This concept of having a comparison or reference point carried over into various scientific disciplines, including experimental design. The idea behind a control group is to have a group that acts as a standard for comparison, allowing researchers to assess the effects or outcomes of an experimental intervention by comparing it to the control group.
