Quantitative

A **quantitative** attribute exists in a variety of magnitudes and therefore it can be measured. Measurements of any kind are expressed as a specific quantity, referred to as a unit and multiplied by a number. Examples of physical quantities include distance, mass, and time. Measurement is the estimation of ratios. Therefore, quantity and measurement are equally defined. This traditional concept of quantity can be traced back to John Wallis and Isaac Newton.
