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.

This slope is greater than zero but less than one, reflecting induced investment. The slope of the investment line affects the slope of the aggregate expenditures line and thus also affects the magnitude of the multiplier process.
