Question

You are planning to evaluate the mean of a single continuous variable from a study with a sample of n = 25 using the t statistic. What are the degrees of freedom for the sample?

Answer 1

Answer: The degrees of freedom (df) for the sample in a t-test are calculated as df = n - 1, where n is the sample size.

In this case, the sample size is n = 25. Therefore, the degrees of freedom for the sample are:

df = n - 1 = 25 - 1 = 24

So, the degrees of freedom for the sample in this case is 24.
