There is one major difference of a treatment group and a control group. The treatment group is treated with an experimental medication (or known medication), and the control group is treated with a placebo in place of the medication to measure effects of the medication.
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.

the control group does not receive receive an experimental treatment but stay in the same environment.
Control groups are non-experimental groups -- that is, they have not been subjected to the experimental treatment. For example, if you are testing a new drug, the experimental group (also called the "treatment group") gets the drug, and the control group does not.Control groups are necessary in order to show that the treatment causes an effect. If the experimental group shows changes, but the control group does not, then it is possible that those changes were caused by the treatment. If there is no control group, then there is nothing to compare the experimental group to.Additionally, a control group is usually given an equivalent treatment. In the drug study, the control group would receive a placebo, such as a sugar pill. In such cases, control groups may be called placebo groups. This is done in order to show that any observed effects are caused by the treatment itself, and not by the process of administering treatment. In this way, we are controlling for the placebo effect -- a psychologically-induced response to a fake treatment, in which people begin to get well because they think they should be getting well.
control group
The null hypothesis is the default hypothesis. It is the hypothesis that there is no difference between the control group and the treatment group. The research hypothesis proposes that there is a significant difference between the control group and the treatment group.

It's not control arm, just control, meaning a control set or group. The control group are individuals that are not given the treatment. If this control group are conscious and can apprehend, every effort is made to make them think they are getting the treatment though they aren't. The reason for the control group is to be able to compare the individuals who have had the treatment (called the experimental group) with others that are in all ways the same except for the treatment and thus see/measure what difference the treatment makes.
A group that receives no treatment is called the control group. The control group is there to compare the results between a group that has been exposed to diffent conditions, and one that has not.

The control group does not change, while the experimental group is the variable you are changing.

Learn about the difference between the control group and the experimental group in a scientific experiment.
A test group is the group in an experiment to which the change is being applied and the control group is the same type of group in an experiment to which nothing is done to compare the changes in the test group to.
ANOVA characterises between group variations, exclusively to treatment. In contrast, ANCOVA divides between group variations to treatment and covariate. ANOVA exhibits within group variations, particularly to individual differences.
