<h3>What is a variable in science?</h3>
A variable is a factor that can be manipulated, changed or controlled while performing scientific experiments.
Variables are of 3 types: independent, dependent and controlled variables.
A dependent variable is the one that changes as a result of manipulating independent variable in experiments.
Independent variable consists of conditions that can be manipulated in experiments and thus affect the dependent variables.
A control group is the one which is used as a standard while performing the experiments. This group contains the normal data to which no manipulations are made.
An experimental group is the one to which we perform experiments. This group receives the treatment and is used to test a hypothesis.
