Median formula: Calculating the median is straightforward

Calculating the median is straightforward if you know the right formulas and how to apply them. In this article, we’ll walk you through how to find the median for both ungrouped data —whether there’s an odd or even number of terms—and how to approach grouped data. As discussed above, the median is one of the measures of central tendency, which gives the middle value of the given data set. While finding the median of the ungrouped data, first arrange the given data in ascending order, and then find the median value. Learn how to calculate the median of a set of data using different formulas for odd and even number of observations. See examples, video lesson and FAQs on median in statistics. At least half of the observations are smaller than or equal to the median , and at least half of the observations are greater than or equal to the median . How to find the Median of numbers ? In order to find the median of numbers , we first need to arrange the given numbers either in ascending order or in descending order of their numerical value.
