The Range

You’ve probably come across the 3 different measures of average

4, 6, 6, 7, 10, 11, 12

Mean = 8
Median = 7
Mode = 6

The range also often gets added onto these 3… although it isn’t actually a measure of the average.

It’s the difference between the largest and smallest value in the data.

So the range here is 12 subtract 4, which is 8
4, 6, 6, 7, 10, 11, 12
Mean = 8
Median = 7
Mode = 6
RANGE = 12 - 4 = 8

The range provides context for the mean, median and mode.

If the range is large, then the mean median or mode might not represent the data very well.

Whereas if the range is small, then they will represent the data well.
