Density statistics definition
WebThe probability density function (" p.d.f. ") of a continuous random variable X with support S is an integrable function f ( x) satisfying the following: f ( x) is positive everywhere in the support S, that is, f ( x) > 0, for all x in S. … WebPopulation density is a statistic that tells you how many people live in a certain area. In general, pop. density is reported in square miles or kilometers, and may or may not include bodies of water. This type of measurement is called arithmetic density, and is reported as the total number of people per land area.
