Variables

Definition

Variables are measurable characteristics, properties, traits, or conditions that can change or vary in quantity or quality during a study. They are usually categorized as independent variables (those manipulated) and dependent variables (those affected by manipulation).

Analogy

Imagine variables as puzzle pieces in your favorite video game. Independent variables are like power-ups that you control; they can impact your character's abilities. Dependent variables are like achievements that change based on how you use those power-ups.

Independent Variable: This term represents the variable intentionally manipulated by the researcher to observe its effect on another variable.

Dependent Variable: Refers to the variable being observed and measured for changes resulting from the manipulation of the independent variable.

Confounding Variable: A third variable that unintentionally influences both the independent and dependent variables, leading to potential inaccuracies in results if not controlled for.
