Population density tells you how crowded a certain area is, on average. To calculate, you need measurements of area, the population count and a calculator.
Continue ReadingChoose the unit of physical space that is to be used. Population density is a measurement of the number of people per unit area. That unit area can be small, such as a neighborhood, or large, such as a country or continent.
A common measurement used when speaking of population density is square mile. Either measure the physical area or locate the length and width from a reliable resource, such as a map.
Learn the population count present within the boundaries of the area. Depending on the size of the area, you might consult official census records to obtain the population count.
The population number is the numerator, and the area is the denominator. Divide the numerator by the denominator to obtain the population density. This figure frequently is expressed in terms of number of people per square mile, for example.
The Greek letter sigma is the commonly used mathematical symbol for population standard deviation. The Greek letter mu is also commonly used in calculations of the population standard deviation for non-overlapping populations.
Full Answer >A confidence interval for a statistical measure (range) is used to quantify the amount of uncertainty associated with a sample estimate of a population parameter. It is computed as Estimate ± Margin of Error. In a 95 percent confidence interval, for example, 95 percent of the samples are within the calculated population parameters.
Full Answer >Sampling, in statistics, is a method of answering questions that deal with large numbers of individuals by selecting a smaller subset of the population for study. One of the most prevalent types of sampling is random sampling.
Full Answer >Parametric testing is defined by making one or more assumptions about the population's properties. The most common assumptions to make are that the population will be normally distributed or have data based on an equal-interval scale.
