- - - - brand of pc/ hair color/ gender/ marital status
    - - discrete
        
        whole numbers
        
        not 1.3 or 3.4
      - continuous
        
        any value within a range
    - - Norminal
        
        don’t have a numeric value
        
        cannot be added, subtracted, divided or multiplied.
        
        can be placed into categories
      - Ordinal
        
        can place in order
        
        Ordinal data codes can be ranked (e.g. 1=Frequently
        2=Sometimes 3=Rarely 4=Never)
        
        Distance between the codes are not meaningful
      - Interval
        
        Intervals between scale points are meaningful (e.g.
        difference between 30°C and 20°C =
        difference between 15°C and 5°C)
        
        Data can be ranked
        
        Mathematical operations can be performed
        
        The absence of a meaningful zero is a key
        characteristic
        
        Special case of Interval Data frequently used in survey
        research is LIKERT SCALE
        
        Number of scale points is typically 5 or 7
      - Ratio
        
        Ratio data have all properties of nominal, ordinal and
        interval data types
        
        Possess a meaningful zero
        
        Ratios of data values are meaningful
