Define Range - Find range from given data



Definition: A Range is the difference between the highest value and lowest value among the given set observations.

Formula:
Range = Highest Value - Lowest Value

Go through the following example to further understanding:

Example 1 - Heights of girls (in cm) in a class are as
146, 121, 127, 149, 131, 135, 125, 141, 151, 137
Find the range of girl's height ?

Answer -
Highest height of girl = 151 cm
Lowest height of girl = 121 cm

Range = Highest height - Lowest height

Range = 151 - 121
Range = 30 cm



Example 2 - Following are the numbers obtained by students in Maths subject:
85, 77, 60, 91, 72, 83, 66, 97, 83, 79
What is the range of the data ?

Answer -
Highest marks obtained = 97
Lowest marks obtained = 60

Range = Highest Marks - Lowest Marks
Range = 97 - 60
Range = 37
