A three-way ANOVA (BMI x grade x gender) was used to
determine the difference in step counts between the different BMI categories, grades, and gender. If main effect was
significant, Least Significant Difference (LSD) post hoc
tests were used to detect further differences. Eta-squared
was used to examine effect size. SPSS 21.0 was used to
perform the data analysis with an alpha level set at 0.05.
