analysis in nvivo 11

Hi all
I have been using nvivo 11 starter version for qualitative analysis of my data. Basically my data has 4 forum groups , which has been classified & coded into nodes and subnodes. I have been trying to focus on one node topic and interested to do quantitative analysis among 4 forum group data. The main idea is to analyse how a particular topic is related among 4 forum groups. May I know what kind of basic statistical test that I need todo ? Is there any suggestion way to do quantitative analysis of above said information . Thanks
