Given the following ANOVA table for three treatments each with six observations:

What is the critical value of F at the 5% level of significance?

Solution

                              
   Degrees of freedom between = k - 1 = 3 - 1 = 2                              
   Degrees of freedom Within = n - k = 18 - 3 = 15                              
                                  
   Degrees of freedom Total F( k-1,n - k,) at 0.05 is = F Crit = 3.682
