Hi, I was wondering if the community can help me understand something. I am trying to finish my thesis which involves a content analysis of a subsample of roughly 104 public comments. I developed a codebook with which myself and a second person can code these comments (codes are the child nodes of the parent node which identifies the variable I am measuring). I want to use Choen's Kappa as a measure of inter-coder reliability and from what I understand, in order to get a coefficient for one node across all sources, I do something similar to the excel sheet found at the bottom of NVivo's FAQ here (Also attached). I understand how Cohen's Kappa works mathematically with an example of two coders and two codes. However, I am having trouble understanding what is going on here with the spreadsheet. I just don't want to copy the formulae and placement without understanding what is being done to get an average kappa coefficient. So my question is this: Can someone break down the spreadsheet for me in descriptive terms? Even understanding What Sum EF, TA and TU would be immensely helpful. Pointing to other resources to lead me the right direction would be great too, unfortunately, I don't have any contacts at my university (and it's summer so feedback is nill anyway) that could help. Thanks in advance!
