Question

You intend to conduct a goodness-of-fit test for a multinomial distribution with 6 categories. You collect data from 76 subjects.

What are the degrees of freedom for the χ2 distribution for this test?
d.f. =

Answer 1

solution:

k = 6

d.f. = k - 1

= 6 - 1

= 5

The degrees of freedom for the χ2 distribution for this test is 5.
