What is the difference between an experimental group and a control group quizlet?
An experimental group is the group in a scientific experiment where the experimental procedure is performed. A control group is a group separated from the rest of the experiment where the independent variable being tested is not exposed.
What is meant by control group and experimental group?
The control group (sometimes called a comparison group) is used in an experiment as a way to ensure that your experiment actually works. The experimental group is given the experimental treatment and the control group is given either a standard treatment or nothing.
Why is it important to have a control group in an controlled experiment?
Why is it important that an experiment include a control group? Without a control group, there is no basis for knowing if a particular result is due to the variable being tested or to some other factor. If it is unknown which group subjects are in, it is less likely that results can be tampered with.

These two groups should be identical in every respect except one: The difference between a control group and an experimental group is that the independent variable is changed for the experimental group, but is held constant in the control group .
Are control groups and experimental groups the same thing?

What is an experimental group and a control group?

How to define control groups in an experiment?
A control group in a scientific experiment is a group separated from the rest of the experiment, where the independent variable being tested cannot influence the results. This isolates the independent variable ‘s effects on the experiment and can help rule out alternative explanations of the experimental results.
