In the investigation of whether stretching before running prevents muscle cramps in calves, the control group would be a group of people who did not do stretching before running.
- In a scientific experiment, a control group is a subset of participants who are not included in the main experiment and whose outcomes are unaffected by the independent variable under study.
- By isolating the effects of the independent variable on the experiment, this can help rule out other possible explanations for the findings of the experiment.
- Positive control groups, untreated control groups, and negative control groups are the three primary categories of control groups.
- Positive control group can demonstrate that the experiment is running as intended.
- Negative control groups are those where the experiment's settings are designed to produce a poor result.
- Untreated control group is merely observed to allow for the comparison of its outcomes of the treatment group.
Thus this is an example of untreated control group where the control group is not given the treatment i.e., stretching before running so that it can be determined whether stretching before running prevents muscle cramps in calves.
