Finding the Mean, Median, Mode and Range The three distinct calculations associated with the Measure of Central Tendency are the Mean, Median, and Mode. Each measurement is an attempt to capture the essence of how a typical entry or number in the data set may look like. The idea is to compute a single value that … Mean Median Mode and Range Read More » The beta distribution of a random variable , where and , has mode , mean , median and variance , which are determined by and in a nonintuitive manner.
