Very random topic for UKC but anyway!
Am just writing up some data and have a few stats related queries as haven't done them in ages...
I am using Fishers exact test with 2 x 2 tables.
So one of my results is:
The 2 variables in the table are:
1 - pt is obese or non-obese
2 - pt has low expression of tumour marker or high expression
Results are:
Low expression - 50 pts are not obese and 12 pts are obese
High expression - 40 pts are not obese and 23 pts are obese.
so the p value is 0.026.
so does ths mean the people with a low expression are MORE likely to be non-obese than those with a high expression? or how do you describe it?
Thanks
