## 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
