case studies - Coggle Diagram

- - - - useful when you are confident in your theory and want to prove it in a hard case
      - researchers must be willing to let it go either way (confirm or reject)
      - uses prior knowledge to test theory outside potential selection bias
    - - takes least-likely case selection further by finding a case that rejects theory
      - can be used to further develop theory or reject it
- - - - cases need to be almost identical- differing in only one particular facet in order to test theory
      - based on Mill's method of agreement
    - - cases need to be almost completely different, sharing only one particular independent variable to see how the dependent variable changes
      - based on Mill's method of difference
    - - create multiple cases out of one case by considering different observation points
      - find different or similar cases and study them over time
