Example Write-Up Potential differences in stress as a function of intervention (not petting a cat, petting a hairless cat, petting a fluffy cat) were evaluated using a one- way, between-subjects ANOVA. The omnibus test revealed a statistically significant overall effect, F(2, 12) = 34.39, p < .001, partial n2 = .85. Tukey's HSD tests were conducted to examine mean differences between the three intervention groups using an overall error rate of .05. Stress scores were significantly higher for those who did not pet a cat (M = 6.00, SD = 1.23) compared to those who petted a hairless cat (M = 1.60, SD = 1.14; p < .001), and those who petted a fluffy cat (M = 0.60, SD = 0.89; p < .001). However, there were not significant differences in stress between those who petted a hairless cat and those who petted a fluffy cat (p = .351). shutterstock.com-46246676 yield ANOVA Sum of Squares df Mean Square F Sig.
