Median formula: To find the median

To find the median, first order the numbers from smallest to largest. Then find the middle number. For example, the middle for this set of numbers is 5, because 5 is right in the middle: 1, 2, 3, 5, 6, 7, 9. You get the same result with the formula . There are 7 numbers in the set, so n = 7: The 4th number in 1, 2, 3, 5, 6, 7, 9 is 5. 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. 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.
