The given ANOVA Table is completed as follows:
Source | Sum of Squares | df | Mean Square | F |
Between Groups | 2376.8 | 3 - 1 = 2 | 2376.8/2=1188.4 | 21.0659 |
Within Groups | 846.2 | 18 - 3 = 15 | 846.2/15=56.4133 | |
Total | 3222.9 | 18 - 1 = 17 |
Correct option:
The three treatment groups differ in SBP.
Explanation:
For Degrees of Freedom (2,15) and = 0.05, critical
value of F = 3.682. Since calculated value of F is greater than
critical value of F, reject null hypothesis and conclude that the
three treatment groups differ in SBP..

A student ran a between-subjects experiment comparing three treatments for depression: cognitive-behavioral therapy (CBT), client-centered therapy (CCT), and a no-treatment condition. Subjects were randomly assigned to the experimental condi- tion. After a sufficient duration on these treatments, the difference in subject’s depression scores pre/post study were measured using a valid depression assessment instrument. The data are summarized in the tables below. Conduct a Oneway ANOVA with α = 0.05 by first completing the values in the lower table, then using...
