Work out the range of 51 38 48 36 39 40 39 and 47

The numerical difference between the maximum and minimum values of a data set.

R = maximum – minimum values

Find the Range

Using our sorted list of numbers

36,38,39,39,40,47,48,51

we subtract the first (smallest/min) from the last (biggest/max)

Range = 51-36 = 15

Median

Definition: the middle (center) value of a data set after the data has been arranged from low to high value. That is, 50% of the data values are below the median value and 50% of the data values are above the median value. A simple formula can be applied. The position (P) of the median is: P=. If n the number of data points is odd, the median value is one of the data points. If n is even, then the median is the average of the data values directly below and above the position calculation. A data set always has a median and it is unique.

Find the Median value

To find the Median value, we begin by sorting Or arranging our numbers In ascending Or descending order.

36,38,39,39,40,47,48,51

Having an even (8) number of values, the median is the midway point between the two middle numbers.

In our case the two middle numbers are 39 and 40

(39+40)/2

Median=39.5
