Compare tool usage (per research activity) for different user groups (discipline, research role, career length, country)

Chi square test
confounding factors?

Idea 1 : clustering of answers.
https://cran.r-project.org/web/views/Cluster.html Probably need to recode into 1 and 0 for every category.

Name          MENDREAD    READCUBE
person 1     1             0                    etc

Can make several distance measures and cluster on them

idea 2: some form of classification or random forests

If you deal with binary data (0 or 1) you will need special tools I think. (random forest do not deal with binary data I think)

For clustering, you often need to set the number of cluster you want a priori.

Maybe the easiest is to set question you want to have answered (difference between humanities and sciences, for example) and then use a PCA and look for a difference on PC1. Careful: you need to set your questions before you touch the data, or you will end up p-hacking your data!
