Given the random sample results above regarding favorite color and years of education, answer the following questions:
What is the within-groups degrees of freedom?
We have here, k = 3 and n = 3*6 = 18
The within-groups degrees of freedom = n-k = 18-3 = 15
i.e. the within-groups degrees of freedom =15
