Question

Calculate the degrees of freedom for a one sample t-test with 2822 US adults between the ages of 15 and 64 in the sample

Answer 1

DF= n-1, n=2822

Answer 2

That's all you have to do?

Answer 3

Yeah, it's the total number of samples. I don't remember the full equation of the t-test, but that's what degree of freedom is

Answer 4

So even if theres say 372 men in a sample and theres 128 million men in the population, the df would still be df= n-1 so df=372-1= 371

Answer 5

right?

Answer 6

yes, because it's only one group. Have to correct myself, it's DF=n- (number of groups being tested) so, since it's between 15 and 64, that's 2. so it would be 2822-2 = 2820

Answer 7

Ohh, you're a genius! I don't know how old you are but you just helped me so much out in my grad school level stats class

Answer 8

I'm a junior bio major. We have to use stats a lot and just learned the t-test last summer.

Answer 9

ahh, well stay at that school! they are way preparing you! i graduated with a communications degree and now going for Masters of Leadership and we're learning this supposedly to help out in studies.

Answer 10

I'm thinking these people are crazy!!!

Answer 11

Wow. Yeah, bio majors have to take a statistics class, but mine was YEARS ago and I don't remember anything. I learned it in one of my bio classes because of our experiments.

Answer 12

Well, good luck! I'm hoping someone will help me with my question. It's calculus, lol.

Answer 13

tell me about it, I did PSO (college in high school) and the Math they put me in was Math for Liberal Art majors... im 22 now and that was when I was like 18... so now you can understand why I was googling HELP WITH STATS HOMEWORK!!!!
