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.
Know MoreChoose 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.
A probabilistic system is one where events and occurrences cannot be predicted with precise accuracy. It is contrasted by a deterministic system in which all events can be predicted with certainty.
Full Answer >A z-score represents the amount of standard deviations a value is away from the mean average. Z-scores are calculated with a probability formula that requires the standard deviation, the population mean and the element value.
Full Answer >The median in that list of numbers is 28. It is the average of the middle two numbers in the list, when the numbers are written in order from least to greatest.
Full Answer >Discrete data refers to specific and distinct values, while continuous data are values within a bounded or boundless interval. Discrete data and continuous data are the two types of numerical data used in the field of statistics.
