– 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
