Explanation:
Detailed explanation-1: -There are three main variables: independent variable, dependent variable and controlled variables.
Detailed explanation-2: -A controlled variable in an experiment is the one that the researcher holds constant or controls. Control variables are the variables or elements that researchers strive to keep constant throughout their research so that they would not influence the outcomes.
