  • Phi and Tetrachoric
    • Used to determine a relationship between two variables that are neither of the interval or ratio scale (e.g., sex and a YES/NO or TRUE/FALSE variable
  • Spearman’s Rho
    • Used primarily for rank ordered data (e.g., likert scales)
  • Eta
    • Used for non-linear relationships only (e.g., age and income)
