Detailed explanation-1: -A variable in an experiment which is held constant in order to assess the relationship between multiple variables, is a control variable.

Detailed explanation-2: -Control variables are held constant or measured throughout a study for both control and experimental groups, while an independent variable varies between control and experimental groups.

Detailed explanation-3: -A controlled variable in an experiment is the one that the researcher holds constant or controls. It is also known as a constant or control variable. The controlled variable is not part of an experiment.

Detailed explanation-4: -In order for a scientist to ensure that only the independent variable is affecting the dependent variable, all the other factors acting upon the test situation (or test subjects) must be kept constant. These factors that must be kept the same are called the controlled variables, or constant variables.

Detailed explanation-5: -The control is the base experiment for comparison with other trials of the experiment. Science experiments also include something called constants. A constant is the part that doesn’t change during the experiment.
