Answer 1

Generally speaking, in any given model or equation, there are two types of variables:

Independent variables - The values that can be changed in a given model or equation. They provide the "input" which is modified by the model to change the "output."
Dependent variables - The values that result from the independent variablesUsing Independent and Dependent Variables

The definition of an independent or dependent variable is more-or-less universal in both statistical or scientific experiments and in mathematics; however, the way the variable is used varies slightly between experimental situations and mathematics.
