1Independent & Dependent Variables
2The Structural Procedure
  1. Independent Variable (x): The input / cause that is chosen or changes freely
  2. Dependent Variable (y): The output / effect that depends on the independent variable
  3. Sentence check: 'The (dependent) depends on the (independent)'
3Mathematical Word Bank
  • independent variable (variable independiente) — The quantity that is subject to choice. It does not depend on the other quantity.
  • dependent variable (variable dependiente) — The quantity that changes in response to the independent variable.
  • depends on (depende de) — One quantity depends on another when changing the first causes the second to change.
  • quantity (cantidad) — Something that can be counted or measured.
  • relationship (relación) — How two quantities change together.
4Watch out
  • Naming the variables backward — calling the responding quantity 'independent' because it is the one the question asks about.
