Definition Definition Middle value of a data set. The median divides a data set into two halves, and it also called the 50th percentile. The median is much less affected by outliers and skewed data than the mean. If the number of elements in a dataset is odd, then the middlemost element of the data arranged in ascending or descending order is the median. If the number of elements in the dataset is even, the average of the two central elements of the arranged data is the median of the set. For example, if a dataset has five items—12, 13, 21, 27, 31—the median is the third item in ascending order, or 21. If a dataset has six items—12, 13, 21, 27, 31, 33—the median is the average of the third (21) and fourth (27) items. It is calculated as follows: (21 + 27) / 2 = 24.

Step 1: Introduction

A data can be raw or grouped, with some pro and cons associated with both of them. The raw data has each and every values and each value has some effect while in grouped data no matter what one does some information is always lost as we don’t have the exact value but the intervals.

The Median is the mid point of the value. The median is the second quartile. The mid point of the first and seconds half of the data with respect to median is first an third quartile respectively.
