Finding effect sizes of ANOVAs

Effect size can be found under the heading Partial Eta Squared in the "Tests of Between-Subject Effects" after running a Univariate Analysis of Variance (ANOVA). Round to two decimal places. Effect size shown is .38.

Interpreting Effect Size

Effect size helps explain how meaningful a result is, beyond whether it is statistically significant. Larger effect sizes indicate a stronger relationship between the variables being studied.

Reporting effect size alongside p-values provides a more complete understanding of research findings, especially in educational and social science research.
