The degrees of freedom for the numerator and denominator for the critical value of F are _3 and 56, respectively_.
The samples, each comprised of 15 observations, were taken from the four populations.

### How to find the degrees of freedom?

The determine the degrees of freedom for the numerator and denominator for the critical value of F is given below:
k = 4
n = 15
Total degree of freedom;
= nk – 1
= 59
For numerator, it is
= k -1
= 4 – 1
= 3
For denominator it is
= T – (k -1 )
= 59 – 3
= 56
The degrees of freedom for the numerator and denominator for the critical value of F are _3 and 56, respectively_.
