A control variable is an element that is not changed throughout an experiment, because its unchanging state allows the relationship between the other variables being tested to be better understood.
What is the definition of a control in an experiment?
When conducting an experiment, a control is an element that remains unchanged or unaffected by other variables. It is used as a benchmark or a point of comparison against which other test results are measured.
What are the different types of controls in an experiment?
The three main types of controls are positive, negative, and experimental controls. A positive control is something known to produce a positive result and will often be included (especially for diagnostic tests) to ensure that a negative result is not due to experimental or reaction failure.
What is a control test in chemistry?
A controlled experiment is a scientific test done under controlled conditions, meaning that just one (or a few) factors are changed at a time, while all others are kept constant. In some cases, there is no good way to test a hypothesis using a controlled experiment (for practical or ethical reasons).
What is a control in science definition?
A scientific control is an experiment or observation designed to minimize the effects of variables other than the independent variable (i.e. confounding variables). This increases the reliability of the results, often through a comparison between control measurements and the other measurements.

A simple example of a control group can be seen in an experiment in which the researcher tests whether or not a new fertilizer has an effect on plant growth. The negative control group would be the set of plants grown without the fertilizer, but under the exact same conditions as the experimental group.
What is the definition of control in science?
Definition of control. a (1) : an experiment in which the subjects are treated as in a parallel experiment except for omission of the procedure or agent under test and which is used as a standard of comparison in judging experimental effects.
