What do you mean by independent and Dependent Variables?

An independent variable is a variable that represents a quantity that is being used in an experiment. The independent variable (sometimes known as the manipulated variable) is the variable whose change isn’t affected by any other variable in the experiment.

X is often the variable used to represent the independent variable in an equation.

A dependent variable is a variable which represents a quantity whose value depends on how the independent variable is manipulated.

The independent variable is what you change, and the dependent variable is what changes because of that.

Y is often the variable used to represent the dependent variable in an equation.
