Detailed explanation-1: -A control variable is an element that is not changed throughout an experiment because its unchanging state allows better understanding of the relationship between the other variables being tested. In any system existing in a natural state, many variables may be interdependent, with each affecting the other.
Detailed explanation-2: -Constant-The factors that do not change during the experiment. Control-The control is the group that serves as a standard of comparison. It is exposed to the same conditions as the experimental group, except for the variable being tested.
Detailed explanation-3: -When conducting an experiment, a control is an element that remains unchanged or unaffected by other variables. It’s used as a benchmark or a point of comparison against which other test results are measured. Controls are typically used in science experiments, business research, cosmetic testing and medication testing.
Detailed explanation-4: -The control variable remains constant throughout an experiment. The independent variable is manipulated during an experiment to hopefully produce the change on the dependent variable in the experiment.
Detailed explanation-5: -Control variables are also called constant or controlled variables. A controlled variable in an experiment is the one that the researcher holds constant or controls.
