A matched control group is a control group whose control group members (matched controls) have each been matched to some treatment group member.
- Context:
- It can reduce the number of members required to achieve stable results by reducing random data skew.
- It can (typically) be assigned during a Matched Control Group Experiment.
- Example(s):
- members are matched for age and gender.
