• Text (alphanumeric)
• Number
– Nominal (e.g. a postal code)
– Ordinal (e.g. order of alluval terrace)
– Cardinal
• With conventional zero (e.g. temperature)
• With real zero (e.g. precipitation)
Text and nominal and ordinal
numbers can only be sorted
No statistic evaluation (such as
central values or dispersion
parameters) is allowed, except for
the evaluation of the modal class
Cardinal numbers with real zero can
be submitted to full statistic analyses
Cardinal numbers with conventional
zero don’t allow ratios
(e.g. 20°C is not the double of 10°C)
