it is the test where a sample is treated like the other experimental groups. IV isn't applied in this.
True
In a scientific experiment, the control group and the experimental group are treated the same way except for the variable being tested. Because the margins of error increase as the sample size gets smaller, both groups should be the same size.
The control group.
it is the groups in experiment
experimental and control
Experimental group and Control group
You need a control group and an experimental group.
In a controlled experiment, there are two groups. The control group is a group that nothing happens to. The experimental group is the group that you subject to the variable with which you are experimenting. At the end of the experiment, you test the differences between the control group, for whom nothing happened, and the experimental group, which received the variable. The difference (or similarities) between the two groups is how your results are measured.A control group is the group used for comparison in an experiment. One group receives the treatment that is being tested by the experiment; another group (the control group) has the exact same controlled environment, but does not receive this treatment. The effectiveness of the treatment can then be established by comparison with the control group.

A control group is not provided any treatment, while the experimental group is the one to which a treatment is applied. The control and experimental groups are chosen to be as similar as possible, so that the observed effect (if any) can be attributed to the variable: what only the experimental group consumes, uses, or participates in.
There are two different types of groups in the experiment, a control group and a experimental group

The variable being tested. The difference between the two groups after the experiment will ideally show some effect by the variable element.
variables
You use a control group to compare the results of the experimental group to. The control group has the "normal" results. After the experiment, you can tell if and what has changed from the control groups results
