A good example would be a drug trial. A randomized controlled trial (or randomized control trial; RCT) is a type of scientific (often medical) experiment that aims to reduce certain sources of bias when testing the effectiveness of new treatments; this is accomplished by randomly allocating subjects to two or more groups, treating them differently, and then comparing them with respect to a measured response.

Because a scientist knows that exercise can lead to weight loss but is only interested in diet, he must ensure that all the subjects get the same amount of exercise to ensure that any difference in weight came from different diets.

The definition of a control experiment is a test where the person conducting the test only changes one variable at a time in order to isolate the results. An experiment where all subjects involved in the experiment are treated exactly the same except for one deviation is an example of a control experiment. A typical use of a control group is in an experiment in which the effect of a treatment is unknown and comparisons between the control group and the experimental group are used to measure the effect of the treatment. For instance, in a pharmaceutical study to determine the effectiveness of a new drug on the treatment of migraines, the experimental group will be administered the new drug and the control group will be administered a placebo (a drug that is inert, or assumed to have no effect). Controlled and Uncontrolled Studies. Some terminology: In a controlled study, researchers are able to determine which of their subjects receive the factor that is being tested for having a causal influence upon another factor. One great example of creating a control in a relatively simple experiment is working with plants. The basis is to determine how plants grow in different types of soil mixtures.
