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, Cohen’s \(d\) = d

A.3 ANOVA

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

A.4 \(\chi^2\)

\(\chi^2\)(n, degrees of freedom) = chi-squared value, p = p-value

A.5 Regression

• Omnibus F-test of the model should be reported as for ANOVA (see above)
• Coefficients: b = coefficient/slope value, t(degrees of freedom) = t-value, p = p-value
