A matched subject design uses separate experimental groups for each particular treatment, but relies upon matching every subject in one group with an equivalent in another. For example, if we merge two . Comparison group: In a non-experiment research design, the group of individuals not receiving the treatment or intervention or receiving an alternative treatment or intervention is called a comparison group.Comparison groups are often used when random assignment cannot be done, and should not be confused with control groups. design — it evaluates the impact of a program by looking at whether the treatment group deviates from its meanbaseline by a greater amount than the comparison group. 16.

Is the occurrence of a response in its freely occurring or natural state, c. Is first obtained prior to the administration of a treatment. Because in this study design, the two groups may not be equivalent (assignment to the groups is not by randomization), confounding may exist. Control groups in scientific research.
