Median is the middle number. In case there are two middle numbers, you can either calculate the average for the result or mark both numbers.20 30 40 50 median is 35 or {30;40}
When there is an even number of items in the data set the median is the mean average of the middle two. The middle two are the two items themselves, namely 20 and 40, so the median is (20 + 40)/2 = 30.
|-20 - (-40)| = 20 |-20 - 10| = 30 -20 is closer to -40 than 10.
