The group of test subjects left untreated or unexposed to some procedure and then compared with treated subjects in order to validate the results of the test
The study patients that did NOT receive the experimental maneuver Subjects who do not receive the drug, test, or intervention under study
A group of research study participants that is essentially similar to the intervention group but is not exposed to the intervention The term denotes that the method of assigning participants to condition (such as intervention or nonintervention group) was by random assignment See comparison group
A control group is a group of participants who receive the standard treatment/care or a placebo At the end of the study, the results of the control group and experimental/intervention group are compared
When scientists carry out experiments to test an hypothesis it is important that all other variables not being tested are kept constant but in most situations this is just not possible Control groups are used instead One group is treated to see the effect of the variable being tested The control group is not treated If the two groups are the same as each other in every other way, then any other changes in the environment will be the same for both groups and the difference between the groups will be due to the variable being tested
A group of individuals in a study who do not receive treatment or are treated in a traditional or regular manner
Participants in a control group are used as a standard for comparison For example, a particular study may divide participants into two groups - an "experimental group" and a "control group " The experimental group is given the experimental treatment under study, while the control group may be given either the standard treatment for the illness or a placebo At the end of the study, the results of the two groups are compared
people in a medical study who do not receive the experimental treatment being tested
A specially selected subgroup of people who purposefully do not receive the same treatment, input or training, etc as the target group Thus, differences between the control group and the target group can be measured and evaluated
The group of patients in a clinical trial who receive either the current standard care or a placebo Results of the control group are compared to results of the treatment group No patient is placed in a control group without treatment if any beneficial treatment is known (See also randomized, controlled research)
(Ticaret) A cycle counting procedure that establishes a given set of parts that will be counted each time a cycle count is performed, usually daily, until each item attains 100% accuracy. Done to uncover procedural and system problems that lead to inventory errors for that family or type of part
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 itself) In medical studies involving the administration of drugs the control group is known as the placebo group A neutral substance ( placebo ) is administered to this group without the subjects knowing if it is an active drug or not
The group of subjects in an experiment that does not receive the independent variable
A group of individuals whose characteristics (such as race/ethnicity, gender, and age) are similar to those of your program participants, but who do not receive the program (services, products, or activities) you are evaluating Participants are randomly assigned to either the treatment (or program) group or to the control group A control group is used to assess the effect of your program on participants as compared to similar individuals not receiving the services, products, or activities you are evaluating The same information is collected for people in the control group as in the experimental group
The arm of a randomized trial which gets the standard treatment In some randomized trials, both of the treatments are standard treatments, or both equally well known new treatments, and in such cases it is not appropriate to speak of a Control Group See also Experimental Group
A group of patients that serves as the basis of comparison when assessing the effects of the intervention of interest that is given to the patients in the treatment group Depending upon the circumstances of the trial, a control group may receive no treatment, a "usual" or "standard" treatment, or a placebo To make the comparison valid, the composition of the control group should resemble that of the treatment group as closely as possible
group of participants in a study to whom no treatment is administered; used as a comparison to the group that receives treatment
