OBSERVATION vs MEASUREMENT #33

Open alistairewj opened 6 years ago

alistairewj commented 6 years ago

The difference between these two tables is subtle:

  1. Numeric/categorical (Quantitative) data in MEASUREMENT
  2. String (Qualitative) data in OBSERVATION

So for example religion/ethnicity are placed in OBSERVATION, while heart rate/respiratory rate are placed in MEASUREMENT.

There are some edge cases worth discussing though.

  1. Scales - for example Glasgow Coma Scale, Pain Scales, etc, which have a numeric component but are also qualitative - reasonably argued to go in MEASUREMENT as these are standardized scales (even if somewhat subjective)

... any other edge cases ?
