simple ways to interprete anova

1. 1. State hypothesis:
H0 : µ1 + µ2 + µ3 + µ4
Ha: At leastone groupmeandiffer
2. Make a decisionbasedon SPSSoutput:
“There was a signification effect of physical activity remembered at the p<0.05 level for
three conditions (F (2, 27) = 8.32 , p = 0.00).”
3. Interpret POST- HOC result:

*. The mean difference is significant at the 0.05 level.
Group 1 (Sedentary and Low) : p >0.092 (statistically not significant)
Group 2 (Sedentary and Moderate ) : p < 0.002 (statistically significant)
Group 3 (Sedentary and High ) : p < 0.001 (statistically significant)

4. Present your report according to APA:
A one way between subject ANOVA was conducted to compare the effect of physical activity.
There was a signification effect of physical activity remembered at the p<0.05 level for three
conditions (F (2, 27) = 8.32 , p = 0.00). Post hoc comparison using the Turkey HSD test
indicated that the mean score for Group 1 , Sedentary and Low ( p >0.092) was statistically not
significant. Group 2, Sedentary and Moderate : p < 0.002 was statistically significant
Group 3 , Sedentary and High (p < 0.001) was statistically significant. However, Group 4 ,
Low and Moderate, (p >0.284) was statistically not significant. Group 5, Low and High (p

3. >0.123) was statistically not significant. Then Group 6 ,Moderate and high ( p >0.952) was
statistically not significant.
