Chi square for comparing more than 2 categories

Discussion in 'Education' started by Nina govaerts, Oct 8, 2018.

  1. I did a retrospective study on complications after 2 types of surgery. My data is catagorised by subtype of complication (bleeding, infection, nerve damage, ...). Can someone tell me if I can perform a chi square test to prove is there is a difference between the 2 types of surgery on complications, because it wouldn't be a 2x2 cross table , but a larger one.
