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.
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.
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.
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.
I still don't know?
A factor that is kept the same between the control and experimental groups is called
the number of participants in both groups are usually the same
yes
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.
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.
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.
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.
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).
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.
The similarity between the experimental group and the control group is that in both cases, results are expected.
the control group does not receive receive an experimental treatment but stay in the same environment.
A control sample or control group is used to compare with the experimental group or sample. The control sample ideally, should be exactly the same as the experimental sample except that you don't give your experimental treatment to the control sample. Afterwards you compare the 2 samples to see if your experimental treatment had any kind of effect. The control is like a reference point.
