- - - - Realtional research questions are about associations between variables
      - Comparative: rqs that make comparisons across groups. They compare the average value of two different variables.
  - - - Fixed - Alternative / structured questions (try to maximise)
      - Open - ended / unstructured response questions (try to minimise)
- - - - Nominal (categorical)
        
        Number only serves as a label or tag for identifying and classifying groups
        
        No rank ordering between variables
        
        counting / frequency
      - Ordinal (categorical)
        
        Numbers are assigned to objects to indicate the relative extent to which the objects possess some characteristic
        
        Rank ordering between values
        
        Frequency, percentiles (quartiles, median)
      - Interval (metric)
        
        Most measures of the strenghts of feelings, emotions, attitudes and beliefs
        
        Rank ordering between values + equal distances on the scale
        
        Frequency, percentiles, mean, stdev
        
        Location or interpretation of 0 is not fixed
      - Ratio (metric)
        
        Provide exact quantity measures of tangible things
        
        Rank ordering values + equal distances + uniform locations of 0
        
        location of 0 fixed
        
        Frequency, percentiles, mean, stdev
