The mean difference is significant at the 0.05 level. What is the variance: a. i. Between groups_ ii. Within groups b. What is F? c. What is the p value? d. State F using APA style_ e. Is there a significant difference among the groups? State the finding in words: f. If appropriate, compute effect size and state the size of the effect_ If the overall result was significant, describe the results of the post hoc tests: g.

Answer 1

a i) variance between groups = 15.896

a ii) Variance within groups = 1.729

b) F = 9.193

c) p = 0.002

e) Here p value is 0.002 which is less than 0.05, so we reject the null hypothesis that there is no significance difference among groups.

g) from post hoc test we found that those groups who has p value near or less than 0.05 have mean difference is zero.

the groups negligible, moderate and severe has mean difference is zero. Because p-values are less than or equal to 0.05
