a group of people who are used for comparing another group to in a test or experiment: The larger the control group sample is, the more reliable and repeatable the results of the promotion will be.

- Quasi-Experimental Design
- Negative Control Groups
- Positive Control Groups
In this research process, every person in the experimental group is matched to one other person based on their environmental and demographic similarities. This is most common when randomly selecting two groups on a broader scale would not result in them being equal. It can help you ensure that the control group or individual continues to act as the...
This is where multiple groups are part of the research, but they are not randomly assigned to test and control conditions. Quasi-experimental designis most common when the groups you are studying already exist, like customers being shown new ad messaging versus non-customers. The control group in this example is made up of your non-customers, as th...
The independent variable does not change in a negative control group. This group represents the true status quo, and you would test the experimental group against it. Examples of negative control groups include many of the experiments listed above, like only changing product packaging or only offering a discount for one group of customers.
In positive control groups, the independent variable is changed where it is already known to have an effect. You would compare this group’s results against those from the experimental group receiving a variation of the same independent variable. This would enable you to determine if the effect changes. In the example of a multi-control group experi...
Introduction. A control group is typically thought of as the baseline in an experiment. In an experiment, clinical trial, or other sort of controlled study, there are at least two groups whose results are compared against each other. The experimental group receives some sort of treatment, and their results are compared against those of the ...
Glossary. control group. In scientific testing, a group of individuals or cases matched to an experimental group and treated in the same way as that group, but which is not exposed to the experimental treatment or factor that the experimental group is.
A control group in an experiment does not receive the treatment. Instead, it serves as a comparison group for the treatments. Researchers compare the results of a treatment group to the control group to determine the effect size, also known as the treatment effect.
Mar 6, 2024 · A control group is a standardized reference group against which the effects of a treatment or intervention are compared. They provide a baseline for assessing the effectiveness of an intervention by allowing researchers to isolate the effects of the treatment from other variables that may influence the outcome.
Dec 16, 2023 · A control group is a fundamental component of scientific experiments designed to compare and evaluate the effects of an intervention or treatment. It serves as a baseline against which the experimental group is measured.
