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.
You test a control group to see what effect the experiment itself has on the participants. The tests must be arranged so that the control group and the experimental group are both going through all the same tests and being given the same information. If you were testing a medication, you would give the control groups placebos. In an ideal experiment not even the testers doing the experiment know who receives the drugs until testing is complete.
To get the right results and avoid getting false-positive results.
Because they need to compare the experimental groups with something.
They have the experimental group in which they experiment on and the control group in which they don't experiment. After they finish experimenting with the experiment group they compare it with the control groups to check what changed and what has been altered between these 2 groups.
A control group is used to show exactly what happens in normal circumstances. The experiment group is the one that is actually tested, then compared to the results of the control group to see what difference if any there is in the results.
a controlled experiment is an experiment that tests only one factor at a time by using a control group and experimental group
The control experiment allows a standard of comparison for the experimental group
A control group is subjected to the same procedures as the experimental group but does not receive the treatment of the independent variable. In the control group all variables are held constant. It is used as a baseline measure. This helps determine whether any of the resulting effects of the experimental group are due to the independent variable treatment and not to the actions involved in providing the treatment.
the experimental group
A blind trial is a trial in which the subject does not know if he is part of the experimental group or the control group. In the case of a pharmaceutical trial, a blind study would be one in which the patients participating in the study would not know if they were being given the actual drug or a placebo. A double-blind trial is one in which neither the patients nor the doctors involved in the study know which patients are in the control group and which patients are in the experimental group.
You need a control group to compare your experimental group to something.
You need a control group and an experimental group.
control group
The control is a group that is held constant and is not experimented with, The experimental group is the group that is experimented with
The control group does not change, while the experimental group is the variable you are changing.
experimental group
The control group.
Experimental group has been exposed to the independent variable whereas the control group has not, and is often used to compare the experimental group's results against.
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.
