Hello,
I am not a statistician, however, for my latest small research, I would like to test whether there is a difference between two independent groups of samples in terms of proportions (one with a condition and one without a condition).
I have researched this problem and find out that different researchers did use two different approaches:
a) z-test to test the difference between two independent proportions
b) chi-quadrate
Now I would like to kindly ask you personal opinion/experience which one is more accurtae in this matter and why ?
Looking forward to hearing (reading) your precious thoughts. Thank you very much !
Cheers,
Zuzana.
