we need to create categories for something like satisfaction (e.g. low, medium, high). If we had continuous scores for this variable we could not analyze it with a chi square analysis.

Lets work on an example to show how some variables can be treated categorically or continuously. Imagine I am conducting a study involving dogs and I want to investigate whether there is a relationship between age and hyperactivity.

Imagine we wanted to conduct a correlation analysis. If we had recorded the dog's ages (e.g. from 0 to 15) and assigned each dog a score from 1 (least hyper) to 10 (most hyper), then we could have conducted this correlation.

However, we can also modify both of these variables to make them suitable for chi square analysis (e.g. change these variables from continuous to categorical).

How specifically would we do that?
