A Canadian startup company is building a database of customers and sales information. For each customer, it records name, ID number, region of the country (1 = West, 2 = Prairies, 3 = North, 4 = Ontario, 5 = Quebec, 6 = Atlantic), date of last purchase, amount of purchase, and item purchased.

Identify the Five W’s, name the variables, specify for each variable whether its use indicates it should be treated as categorical or quantitative, and for any quantitative variable identify the units in which it was measured (or note that they weren’t provided or that the variable doesn’t have units).
