In conducting a scientific experiment, a scientist should have a control group and an experiment/treatment group. The scientist proposes a null hypothesis (null because it is intended to be disproven). The scientist then treats the two groups identically except the treatment group receives the treatment and the control group does not. Because the two groups were treated identically except for the treatment, any subsequent differences in the groups is (tentatively) attributed to the treatment. Thus,the control group is the group NOT receiving the treatment. For example, the scientist could propose that "fish will not die if they stop receiving food" (as a null hypothesis). The scientist then places two fish tanks full of similar fish into the same room, so that temperature, air pressure and light are equal. Then the scientist feeds one tank the recommended amount of fish food, while not feeding the other tank at all. After one week of this treatment, the scientist observes the tank receiving food (the control group) contains live fish while the group receiving the treatment (starvation) only contains dead fish. The scientist would then disprove the null hypothesis and conclude (tentatively) that fish do need food to continue living.

What is purpose of a control group?
The purpose of a control group in an experiment is to provide a baseline for comparison with the group that receives the experimental treatment. By having a control group that does not receive the treatment, researchers can better determine the effect of the treatment being studied. It helps to ensure that any observed changes are a result of the treatment and not due to external factors.
What is a control group?
A control group is a group in an experiment or study that does not receive the treatment under investigation. It is used as a standard of comparison to evaluate the effectiveness of the treatment being tested. The control group helps researchers determine if changes observed in the experimental group are due to the treatment itself or other factors.
The group that does not receive the experimental treatment in an experiment is the?
control group
What is the differen ce between a control group and a variable group?
A control group is a group that does not receive the experimental treatment and is used as a baseline for comparison, while a variable group is a group that is exposed to the experimental treatment. The control group helps researchers determine the effect of the treatment by providing a reference point.
Are control groups and experimental groups the same thing?
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.
What is the importance in having a control group?

What is the purpose of a control group?
The defintion of a control group in an experiment is a standard for comparison. So then the purpose of the whole control group during an expirenment is to have something to compare your data to.
What is the purpose of the control group in a controlles experiment?
Experiments typically use control groups. One group of people are manipulated and measured, while the control group just stays as they are. The control group is measured against the manipulated group to see what changes.
What is the purpose of the control group?
The purpose of a control group is to show what would happen under normal conditions. It serves as a comparison to the results you receive from the manipulation of the independent variable on the dependent variable. If a control group is present in an experiment, one can be more certain that the independent variable is really responsible for the observations.
In an experiment what is the purpose of ta control?
The control group stays the same throughout the entire experiment.
What is purpose of having a control in a experiment?
Having a control in an experiment allows you to see what happens when no variables are changed. If you do not have a control, you do not have anything to compare your results with after changing variables of the experiment.
What is purpose of a control group?
The purpose of a control group in an experiment is to provide a baseline for comparison with the group that receives the experimental treatment. By having a control group that does not receive the treatment, researchers can better determine the effect of the treatment being studied. It helps to ensure that any observed changes are a result of the treatment and not due to external factors.
What is an organisation about?
organization is a group of people having one purpose or goal for the betterment of them and the community.
What is the purpose of the Terrier group?
Terrier dogs were bred to control mice, rabbits, foxes and badgers.
What is the purpose of having a control in an experiment?
I can best explain through example. Let's say that you are sea sick. You take two remedies, an acupressure bracelet and 50 milligrams of meclizine. You quickly start to feel better, but which of the two factors made the difference? The bracelet? The meclizine? A combination of both? This is a small-scale example, but in the fields of science it becomes important to know what causes a certain affect. This is the reason that we use controls.-Akilae
What are the branches of the Texas government and what is the purpose of different branches?
