Subject: Significance testing for corpus comparison

 
Dear linguists,

I am working on a corpus containing Wikipedia articles and articles from
printed encyclopedias. I would like to study differences in style between
Computer Mediated Discourse and written discourse. My corpus contains articles
from 4 disciplines and it is thematically comparable because I always chose
the same lemma. 

I also calculated relative frequencies and now I ask myself how to find out
the most typical words for each subcorpus (Wikipedia vs. printed
encyclopedias). For this purpose I ask the question if statistical methods
like significance testing could help here. I read about LL-test, chi square
and also non-parametric tests. 

Now: Which test should I apply for my research question or should I rely on
other measures?

Thank you for your answers,
Bettina Eiber
