What kind of statistics to use?
Posted 26 June 2011 - 01:26 PM
I would like to ask for some advice with how to statistically analyze my data.
I have 3 specimens from 25 patients taken at the beginning of their disease, when they clinically improve and at the time of release from hospital. In all three specimens I measured the expression of gene of interest. Now I want to know whether there is a sex-deppendent difference in the disease course represented by differences in gene of interest expression. In other words, I would like to analyze differences among times of sampling in male and female patients.
The only way how I am able to do that is to count median (non-Normal distribution) for all three sampling times for men and women and compare these 3 and 3 median values by Mann-Whitney statistics. But this is too simplified I guess and I am loosing much of variability in each group. What would be the proper way to statistically compare my data?
Thank you in advance for any suggestion.
