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.

Does a control group receive experimental treatment?
the control group does not receive receive an experimental treatment but stay in the same environment.
What is a control group in psychology?
A control group is usually used in experimental psychology to study the effect of an intervention or treatment. Research in psychology covers a number of topics. Sometimes, in order to verify whether an effect is significant, it is necessary to compare two groups or more. One of these groups will be a control group. A control group will often present the same characteristics as the other groups but will not be exposed to treatment or intervention, contrary to its counterpart(s). For example, group A can receive a newly developed therapy for depression, whereas the control group will not receive this therapy. Later on, both depressed groups will be compared to determine if the therapy had a significant effect, or, in other words, if it worked. Another example pertains to social therapy. A researcher could study the effect of setting short terms realistic goals on attaining long term goals. As such, a group of students would receive help on how to set short term goals, how to reach them, how to deal with obstacles, etc to attain long term goals. The control group, also made of students, would not receive such an intervention and would be told to set up long term goals and try to achieve them. At the end of the research period, both groups would be compared to see whether the intervention in helping setting short term goals and achieving them made a difference in term of goal achievement.
What is a experimental question?
Actually an experimental question ia a hypothesis which means and educated guess or you could call it a prediction which actually is kinda the same definition.
Why do you have to keep all conditions the same in the control group?
The sole purpose for a control group is so the researcher can compare his/her results with the experimental group in order to prove his/her hypothesis is correct by showing conditions before they have changed any variable. in order to achieve this and make it fair all conditions must be kept the same in order to make a fair comparison.
What is the purpose of having a control group?
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 factor is kept the same between the control and experimental groups is called?
A factor that is kept the same between the control and experimental groups is called
What are things that are both the same for experimental and control groups?
the number of participants in both groups are usually the same
The control and experimental groups are treated exactly the same in an investigation yes o no?
yes
What is the difference between a control group and an experimental group?
Control groups do not test the variable or action. They are a constant comparative base. The experimental group has one different variable. They two are compared to see what affect (if any) the variable has. The control group is not exposed or subjected to what they're testing. The experimental group is. For example, a control group and an experimental group may each consume the same foods, on the same schedule. The experimental group would also receive a nutritional supplement, to see if it had any beneficial effect. This would ideally be the only major difference in the two groups.
What is the constant variable in investigation of fungi growth mold?
The variables that you keep the same between the control and experimental groups are the constant variables.
What do you call the variable that must remain the same between two groups?
The variables that must remain the same between the control group and experimental group is are called controlled variables, and include everything except the experimental variable.
Why should the sample size of the control group be the same as the size of the experimental group?
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.
Why do you need a control group and a experimental 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.
Does a control group receive experimental treatment?
the control group does not receive receive an experimental treatment but stay in the same environment.
What is a experimental group?
In a scientific experiment it is common to split your sample into (at least) two groups. Say you were to study the effect of a new drug on a specific condition, you would have a sample (a group of people with the condition in question e.g. breast cancer), and you would treat all members of the sample the same, with the exception that one group is give the actual drug, and the other group is given a "fake" pill. This fake pill is also called a placebo. The group that is given the real drug is called the experimental group, and the group that is give the placebo is called the control group. This setup attempts to ensure that any effect that is observed is caused by the drug (the experimental condition).
What are the difference between control set up and variable experimental set up?
The control variable is the thing you keep the same and is everything that is not the independent variable. The Control Setup is there for the sake of comparison.
What is the same between the experimental and control group?
The similarity between the experimental group and the control group is that in both cases, results are expected.
