Find the range of heights of any ten students of your class.

Dear Student

Let us assume heights (in cm) of 10 students of our class.
= 130, 132, 135, 137, 139, 140, 142, 143, 145, 148
By observing the above mentioned values, the highest value is = 148 cm
By observing the above mentioned values, the lowest value is = 130 cm Then,
Range of Heights = Highest value–Lowest value
= 148–130
= 18 cm

Thanks
