Answer:
The correct answer is c. Partial eta squared as a measure of effect size is referenced last in an APA formatted statistical report of the results regarding a two-factor ANOVA.
APA (American Psychological Association) style is commonly used in social sciences research to report statistical analyses. In a two-factor ANOVA, the results are typically reported in a specific order, following APA guidelines.
First, the F-ratio and degrees of freedom (df) for the F-ratio test are reported. Then, the means and standard deviations for all factor conditions are reported. Finally, the effect size measure, such as partial eta squared, is reported.
Therefore, option c (partial eta squared as a measure of effect size) is the bit of information referenced last in an APA formatted statistical report of the results regarding a two-factor ANOVA.
