Question

A researcher conducts a two–independent sample t-test with a sample of 24 participants, where 12 participants are observed in each group. What are the degrees of freedom for this hypothesis test?

Answer 1

22

Explanation:

here we have given 12 participants in each group so
`n_1=12\ and\ n_2=12`

we have to find the degree of freedom of this hypothesis

we know that degree of freedom of hypothesis is given by
`n_1+n_2-2`

so by using this formula

degree of freedom of hypothesis =
`n_1+n_2-2`=12+12-2=22

so the degree of freedom of hypothesis will be 22
