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.

∙ 13y agoYou test a control group to see what effect the experiment itself has on the participants. The tests must be arranged so that the control group and the experimental group are both going through all the same tests and being given the same information. If you were testing a medication, you would give the control groups placebos. In an ideal experiment not even the testers doing the experiment know who receives the drugs until testing is complete.
To get the right results and avoid getting false-positive results.

They have the experimental group in which they experiment on and the control group in which they don't experiment. After they finish experimenting with the experiment group they compare it with the control groups to check what changed and what has been altered between these 2 groups.

In an experiment a group that is identical to a control group except for one factor and that is compared with the control group?
a controlled experiment is an experiment that tests only one factor at a time by using a control group and experimental group
Why is it important to control an experiment?
The control experiment allows a standard of comparison for the experimental group
Why is a control group needed?
A control group is subjected to the same procedures as the experimental group but does not receive the treatment of the independent variable. In the control group all variables are held constant. It is used as a baseline measure. This helps determine whether any of the resulting effects of the experimental group are due to the independent variable treatment and not to the actions involved in providing the treatment.
What is the group that receeives the experimental treatment?
the experimental group
What is a blind trial?
A blind trial is a trial in which the subject does not know if he is part of the experimental group or the control group. In the case of a pharmaceutical trial, a blind study would be one in which the patients participating in the study would not know if they were being given the actual drug or a placebo. A double-blind trial is one in which neither the patients nor the doctors involved in the study know which patients are in the control group and which patients are in the experimental group.
Why do you need a a control group?
You need a control group to compare your experimental group to something.
What are the two groups you need to have an experiment?
You need a control group and an experimental group.
In an experiment the group that is exposed to the variable to be tested is called the?
control group
What is the difference between a control groups and experimental groups?
The control is a group that is held constant and is not experimented with, The experimental group is the group that is experimented with
What is the different between a control group and an experimental group in an experiment?
The control group does not change, while the experimental group is the variable you are changing.
The group of experimental subjects which is left natural or left unchanged is called the?
experimental group
In a controlled experiment what is the experimental group compared to?
The control group.
What is the difference of control group and the experimental group?
Experimental group has been exposed to the independent variable whereas the control group has not, and is often used to compare the experimental group's results against.
What is the difference between the control group and the experimental group in a controlled experiment?
The control group does not change, while the experimental group is the variable you are changing.
What is difference between the control group and the experimental group in a controlled experiment?
The control group does not change, while the experimental group is the variable you are changing.
