Quantification (science)

In mathematics and empirical science, quantification (or quantitation) is the act of counting and measuring that maps human sense observations and experiences into quantities. Quantification in this sense is fundamental to the scientific method.

Some measure of the undisputed general importance of quantification in the natural sciences can be gleaned from the following comments:

This meaning of quantification comes under the heading of pragmatics.

In some instances in the natural sciences a seemingly intangible concept may be quantified by creating a scale—for example, a pain scale in medical research, or a discomfort scale at the intersection of meteorology and human physiology such as the heat index measuring the combined perceived effect of heat and humidity, or the wind chill factor measuring the combined perceived effects of cold and wind.

In the social sciences, quantification is an integral part of economics and psychology. Both disciplines gather data—economics by empirical observation and psychology by experimentation, and both use statistical techniques such as regression analysis to draw conclusions from it.
