Statistics

Cohen is using the first person singular more than the second person plural.Can we really conclude that he is interested in himself and not the relationship? I decided to compare my results with the results from FROWN, which is a large(ish) corpus of North American English from the 70s and 80s, to see if his language usage is different from 'the norm'. No conclusions yet. Am I going to need statistics to interpret this? Or will it just be 'obvious'? Even when I was a graduate mathematician in my younger life, I did not 'get' statistics and now I want to avoid them at all costs. Pathetic!!
