Okay I have this question which is probably VERY simple to most of you but I can not find an example with a number 2 in it so thought I would ask you all......

F(2,147)

How many groups are in this study and what is the sample size???

Thanks in advance........
 
Okay maybe this would help...the full equation is:

F(2,147)=4.56,p=0.003 (though the example the book gave never used the 2nd part to figure out the groups and the sample size........

their example was F(1,343)........they stated 1 is the group degrees of freedom calculated K-1 (where K is the number of groups....K-1=2-1=1........I just dont know how do you know what K is??????
 
I think its like this

for the 1st degree of freedom its number of groups less one

for the 2nd its sample size less number of groups


1+1=2 there were 2 groups

147+2=149 was the sample size
 
Thanks for the response in the example they said the f(1,343) had 2 groups and once they figured out the groups they just subtracted it from the 343.... so the f (2,147) has to be more than 2 groups right????
 
ya, I got the examples mixed up

f(2,147)

2+1=3 groups
147+3=150 sample size
 
Okay thank you for helping me figure it out! i have been stressing over it for days now! :) Thanks again!
