You have two independent samples of size 24 and 27. You conduct a hypothesis test and obtain a p-value. Using the conservative method what would you use for the degrees of freedom for comparison?
24
27
23
26
49
Degrees of freedom =
n1 + n2 - 2 =
24 + 27 - 2 = ?
I'll let you finish.
^ This person is wrong. That's not the formula for a 2-samp degree of freedom.
To determine the degrees of freedom for comparison in this scenario, you would follow the conservative method. In this method, you use the smaller sample size minus 1 as the degrees of freedom.
Therefore, from the given information, the smaller sample size is 24. So you would use 24 - 1 = 23 as the degrees of freedom for comparison.
Hence, the correct answer is 23.
