How do you know if data is numerical or categorical?

Qualitative or categorical data have no logical order, and can't be translated into a numerical value. Eye colour is an example, because 'brown' is not higher or lower than 'blue'. Quantitative or numerical data are numbers, and that way they 'impose' an order. Examples are age, height, weight.
