RESEARCH METHODOLOGY

Detailed explanation-1: -Variables are elements, entities, or factors that can change (vary); for example, the outdoor temperature, the cost of gasoline per gallon, a person’s weight, and the mood of persons in your extended family are all variables.

Detailed explanation-2: -An experiment usually has three kinds of variables: independent, dependent, and controlled. The independent variable is the one that is changed by the scientist.

Detailed explanation-3: -A confounding variable influences the dependent variable, and also correlates with or causally affects the independent variable. Confounding variables can invalidate your experiment results by making them biased or suggesting a relationship between variables exists when it does not.

Detailed explanation-4: -The independent variable is the variable the experimenter manipulates or changes and is assumed to directly affect the dependent variable. For example, allocating participants to drug or placebo conditions (independent variable) to measure any changes in the intensity of their anxiety (dependent variable).
