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.
40 (+20, -10, +30 ,-20)
Take your pick; 10 and 20, 10 and 30, 10 and 40, 10 and 50, 10 and 60, 10 and 70, 10 and 80, 10 and 90, 20 and 30, 20 and 50, 20 and 70, 20 and 90, 30 and 40, 30 and 50, 30 and 70, 30 and 80, 40 and 50, 40 and 70, 40 and 90, 50 and 60, 50 and 70, 50 and 80 50 and 90, 60 and 70, 70 and 80, 70 and 90, 80 and 90.
range - 59 median- 35
10 plus 20 plus 30plus 40 plus 50 equals 150 because 50 plus 40 equals 90 plus 30 =120+20= 140 then + 10 = 150
90
It is: 35

These may help you answer your questions: 1, 2, 4, 5, 8, 10, 20 and 40.
The answer can be shown by adding the two middle numbers (30 and 40), and dividing by 2. The answer is 35. :)
10, 10, 20, 30, 30, 50.
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.
