Appendix A — APA reporting style for statistical tests

A.1 Correlation

  • Pearson’s \(r\): r(degrees of freedom) = correlation coefficient, p = p-value

A.2 t-tests

  • t(degrees of freedom) = t-value, p = p-value, d = cohen’s d

A.3 ANOVA

  • F(numerator/effect degrees of freedom, denominator/residual degrees of freedom) = F-value, p = p-value, \(\omega^2\) = omega-squared value

A.4 \(\chi^2\)

  • \(\chi^2\)(n, degrees of freedom) = chi-squared value, p = p-value, V = Cramer’s V value

A.5 Regression

  • Coefficients: b = coefficient/slope value, t(degrees of freedom) = t-value, p = p-value
  • With many coefficients, a table can be more efficient

A.5.1 Mediation

  • Coefficients and tests for different paths can be reported as for standard regression
  • if using bootstrapped and bias-corrected confidence intervals (e.g., as produced when using PROCESS), then: b = coefficient/path value, 95% BCa CI = [CI lower bound, CI upper bound]

A.5.2 Moderation

  • Coefficients and tests (including those from simple slopes analyses) can be reported as for standard regression
  • With many coefficients, a table can be more efficient
