Tables and Correlations

• 2 by 2 tables easy (?) to understand

  • counts of patients
  • conventional framework for clinical research

• Correlation easy (?) to understand

  • ranges from -1 to 1
  • 0 means no relation

• Therefore an approach constructed from these concepts will be easy for clinicians to use to deal with non-independent symptoms

• Limitation: Applicable only with two tests.
