The Range is the difference between the highest and lowest value in a group of data. The method to find out the range is by subtracting the lowest value from the highest value from a set of data.
Eg)
From the set of data below, can you work out the range value?
5,8,18,4,15,47,6,13,34,12,9,3,2,6,4,48
ANSWER The highest value in the set is 48 and the lowest value in the set is 2. So to find the range,we have to subtract the lower value from the highest value. 48-2=46(the range)
