In ANOVA, the observed value of the F statistic has following numerator degrees of freedom ( Note: k= number of groups in the sample, n= total sample size)

a)n - k

b) k - 1

c) n - 1

d) k

e) none of the above

Solution

[ANSWER] k= number of groups in the sample, n= total sample size)
b) k - 1  

Degrees of freedom between = k - 1
Degrees of freedom Within = n - k
  
Degrees of freedom Total F( k-1,n - k,) at 0.05 is = F Crit
