Given below are the analysis of variance results from a Minitab display. Assume that you want to use a 0.05 significance level in testing the null hypothesis that the different samples come from populations with the same mean.
Identify the value of the test statistic.
 
   
| Source | DF | SS | MS | F | P | 
| Factor | 3 | 30 | 10.00 | 1.6 | 0.264 | 
| Error | 8 | 50 | 6.25 | ||
| Total | 11 | 80 | 
Solution
test statistic is F = 1.6
Since p-value = 0.264 is not less than 0.05, we fail to reject null, and conclude that there is not significant difference in means of 4 groups.
