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

The control group does not change, while the experimental group is the variable you are changing.
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 experimental group receives the treatment or intervention being studied, while the control group does not receive the treatment and is used for comparison. This is the primary difference between the two groups in an experiment.
You can select more than one HtmlInputCheckBox control from a group of HtmlInputCheckBox controls; whereas, you can select only a single HtmllnputRadioButton control from a group ofHtmlInputRadioButton controls.
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.
