English Language Investigation. Help!!!?

I'm in year 13 and I have to carry out a language investigation. My draft has to be in by Thursday and I am just at a loss with it. I'm studying language change in three different bible editions (King James, Children's Bible and a 1984 Holy Bible). I've done some pie charts showing number of nouns, conjunctions etc etc and now I'm on to the ysis. I found a few archaisms and differences in decriptions but aside from that I haven't a clue. I am really really stressed and would be so grateful if anyone has any ideas as to what I could comment on/ look into?
