Question
Find the range of heights of any ten students of your class.
Solution
Let the heights (in cm) of 10 students of our class be
125, 127, 132, 133, 134, 136, 138, 141, 144, 146
Highest value among these observations = 146
Lowest value among these observations = 125
Range = Highest value − Lowest value
= (146 − 125) cm
= 21 cm
