Draft:Rule of Five (statistics)


In statistics the rule of five is a statistical rule of thumb used to quickly estimate the median of a population. It states that there is a 93.75% chance that the true median of a population lies between the smallest and largest values in any random sample of five taken from that population.

The rule of five offers a way to reduce uncertainty and make faster business decisions without extensive data collection. Instead of surveying an entire population, the rule of five involves selecting a random sample of five members to represent the population. This statistical tool is used across disciplines like business research[1], software engineering[2], statistical computing[3], data analytics[4], and social research[5].
