# Find the range of heights of any 10 students of your class.

**Solution:**

Let us assume the heights (in cm) of 10 students of our class as :

120, 122, 125, 137, 139, 150, 142, 133, 145, 158

By observing the above-mentioned values, the highest value is = 158 cm

By observing the above-mentioned values, the lowest value is = 120 cm

The range is the difference between the highest value and the lowest value of the data. It helps in knowing the spread of the data.

Then,

Range of Heights = Highest value – Lowest value

= 158 – 120

= 38 cm
