A group in an experiment that receives not treatment in order to compare the treated group against a norm.

A group of subjects in an experiment who are not exposed to any of the experimental treatments or alternatives whose effects are to be measured; the control group is used to assess what part of the total observed effect was due to things other than the experimental variable(s).

A group of people in a study who do not have the intervention or test being studied. Instead, they may have the standard intervention (sometimes called 'usual care') or a dummy intervention [..]

A comparison group of study subjects who are not treated with the investigational agent. The subjects in this group may receive no therapy, a different therapy, or a placebo.

The subjects in a controlled experiment who do not receive the treatment.

The group of subjects in an experiment that does not receive the independent variable.

A group that does not receive the experimental intervention. In many studies, the control group receives either usual care or a placebo.

In scientific testing, a group of individuals or cases matched to an experimental group and treated in the same way as that group, but which is not exposed to the experimental treatment or factor that [..]

An observed, unmanipulated set of test subjects. In an experimental manipulation, we must also perform the actions involved in that manipulation on a second test group of organisms in order to ascertain whether any effects of the experimental treatment are due to that treatment and not to the actions involved in providing the treatment. control rod [..]

A control group is one of three sets of parameters which measure the performance of a test method. The three sets of control parameters are the method controls, the control specimens, and the subpopulation distributions.

In an experiment, the control group does not receive the intervention or treatment under investigation. This group may also be referred to as the comparison group.

Participants who do not receive the experimental treatment

A control group (of cells, individuals or centres, for example) serves as a basis of comparison in a study. In this group, no experimental stimulus is received.

A group of people in a medical study who receive either no treatment or the standard treatment, which is compared against a group who receive the treatment being studied.

A group of subjects which does not receive the experimental treatment but in all other respects is treated in the same way as the experimental group, (so as to tease out the effects of the treatment i [..]

Groups that serve as a standard for comparison in experimental studies. They are similar in relevant characteristics to the experimental group but do not receive the experimental intervention.

A group of subjects not exposed to the presumed crucial value of the independent variable.

Those subjects who are exposed to control or nonexperimental conditions so as to provide a basis for comparison to the performance of subjects exposed to experimental or treatment conditions.

In a clinical trial, the group that does not receive the new treatment being studied. This group is compared to the group that receives the new treatment, to see if the new treatment works.

In a clinical trial, the group of people that receives the best standard treatment for their cancer.

Sometimes called a "comparison group", this group does not receive the intervention being evaluated and allows the evaluator to estimate what would have happened if the treatment group had not received the intervention. The control group should be as similar to the treatment group as possible before the intervention is applied. Th [..]

A group of people or an area that is similar to the treatment group or area, but does not receive treatment. Used in evaluations to control for the impact of other, non-treatment influences on crime (see Controls [for analysis]).

The control group of a study is a group that receives a treatment other than the one being studied (for instance, a placebo pill that looks identical to the medication being studied but that has no ac [..]

The comparison group in drug-trials not being given the studied drug.

Used as a basis of comparison to one or more treatment (or experimental) groups, a control group is a comparable group of participants that is not exposed to the experimental treatment or intervention.

A group chosen randomly from the same population as the program group but that does not receive the program. It is a stand-in for what the program group would have looked like if it had not received t [..]

In an experimental design, which is contrasting two or more groups, the control group of subjects is not given the treatment whose effect is under investigation.

A group of patients that is compared with a group receiving the experimental treatment. In a clinical trial, the control group receives the control treatment.
