an control group is when an experiment is conducted for the purpose of determining the effect of a single variable of interest on a particular system.
The part of your experiment that you don't do anything different to.The conditions stay normal.
A control group is used as a base line for comparison to experimental results.
is a standard on which change can be measured.
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.
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.
a control stays the same(under control) but the variable almost always changes
In such cases the group is called the control group.
the control group does not receive receive an experimental treatment but stay in the same environment.
The control group in an experiment is the group that nothing is done to. The reason why there is a control group in experiments is to compare it with the group that has been tested.
You use a control group to compare the results of the experimental group to. The control group has the "normal" results. After the experiment, you can tell if and what has changed from the control groups results
the group that does not change in the experiment VIVI :)
The control group is used for exprimenting
You need a control group to compare your experimental group to something.
A control group is the unaffected group in a science experiment.
He needed a control group. *Apex*
A control refers to the "control group" in a scientific experiment. The control group is compared to the experimental group. For example, pretend you are experimenting to see if a drug works. Group A (The experimental group) is given the real drug, and Group B (The control group) is given a fake drug (placebo) to compare results.
the control group is the group or subject that is not affected by what you are testing for.
control group
A control group is nothing changed about it
the control group is recieving the medication
