The median often gives a more accurate representation of the data set than simply finding the average (or mean) might. If your three kids have $2, $3 and $25 in their piggy banks, respectively, each child would have an average of $10. But the truth is, only one of the kids is a...
The median is the middlemost number of a group of numbers that have been arranged in order by size. Learn how to find median for ungrouped and grouped data using different formulas along with solved examples here at BYJU'S.
