Document Summary
N: another criterion: non-numerical, qualitative, cannot rank a nominal variable, e. g. religious affiliations. O: all features of nominal, except, can be numerical/non-numerical, no restrictions: qualitative/quantitative, can be ranked. E. g. low income, middle income, high income (qualitative) 0 - 10 000 (quantitative: distance between categories are not fixed, e. g. 0 - 10 000; 10 001 - 15 000; 15 001 - 49 999 (not fixed distances) I: always numerical, can be logically ranked. Interval & ratio = continuous: categories run into each other, e. g. Age: 1, 2, 3, 4, 5, 6, 7 (keeps going: fixed distances, 0 is not a true 0, 0 does not mean the absent of what you"re looking for, e. g. 0 on iq test, doesn"t mean you completely lack intelligence: e. g. temperature 0 - does not mean there is no heat at all (not true 0) 0 - true zero: total absence of money, can draw mathematical inferences b/w attributes of variable, can state rate of difference.
