In statistics, a standard normal table, also called the unit normal table or Z table, [1] is a mathematical table for the values of Φ, the cumulative distribution function of the normal distribution.
Population density (people per km 2) by country. This is a list of countries and dependencies ranked by population density, sorted by inhabitants per square kilometre or square mile. The list includes sovereign states and self-governing dependent territories based upon the ISO standard ISO 3166-1.
Comparison of the various grading methods in a normal distribution, including: standard deviations, cumulative percentages, percentile equivalents, z-scores, T-scores. In statistics, the standard score is the number of standard deviations by which the value of a raw score (i.e., an observed value or data point) is above or below the mean value of what is being observed or measured.
This population cartogram of the European Union (2007–2012) uses areas and colors to represent population. Living population density by country. Although the arithmetic density is the most common way of measuring population density, several other methods have been developed to provide alternative measures of population density over a specific ...

This is a special case when = and =, and it is described by this probability density function (or density): =. The variable z {\textstyle z} has a mean of 0 and a variance and standard deviation of 1.
This is a list of cities worldwide by population density. The population, population density and land area for the cities listed are based on the entire city proper, the defined boundary or border of a city or the city limits of the city. The population density of the cities listed is based on the average number of people living per square ...
This is a list of countries showing past and future population density, ranging from 1950 to 2300, as estimated by the 2017 revision of the World Population Prospects database by the United Nations Population Division. The population density equals the number of human inhabitants per square kilometer of land area.
