CARDINAL: A measurement based on a scale or quantitative numbers, such as 1, 5, or 357.2, that enables a comparison in magnitude. Comparability means, for example, that the difference between 5 and 2 is the same as the difference between 12 and 9. Measures such as height and weight use cardinal numbers. Most economic measures are based on cardinal numbers, including gross domestic product, unemployment rate, the price of chocolate, and the quantity of wheat produced. The benefit of cardinal measurement is the ability to directly compare one measure with another. If, for example, the price of chocolate is $1 a pound and the price of wheat is $4 a pound, then wheat is four times more expensive than chocolate. Ordinal measures, which involve relative ranking, is an alternative type of measure.

MARGINAL PRODUCTIVITY THEORY A theory used to analyze the profit-maximizing quantity of inputs (that is, the services of factor of productions) purchased by a firm in the production of output. Marginal-productivity theory indicates that the demand for a factor of production is based on the marginal product of the factor. In particular, a firm is generally willing to pay a higher price for an input that is more productive and contributes more to output. The demand for an input is thus best termed a derived demand.
