Eight observations were selected from each of 3 populations (total of 24 observations), and an analysis of variance was performed on the data. The following are part of the results.
Source of Variation | Sum of Squares | Degrees of Freedom | Mean Square | F |
Between Treatments | 216 | | | |
Within Treatments | 252 | | | |
(Error) | | | | |
Using α = .05, test to see if there is a significant difference among the means of the three populations.
