Question

If you conduct a t test for independent means, how many degrees of freedom are in the t distribution?

1) 24
2) 55
3) 56
4) 61

Answer 1

The degrees of freedom in a t distribution for an independent t test depend on the sample sizes of both groups being compared.

Step-by-step explanation:

The degrees of freedom in a t distribution for an independent t test are determined by the sample sizes of both groups being compared.

The formula to calculate the degrees of freedom is df = n1 + n2 - 2, where n1 is the sample size of the first group and n2 is the sample size of the second group.

Therefore, if the question does not provide the sample sizes of the groups, we cannot determine the degrees of freedom.
