Question

The following are the temperatures (in degrees centigrade) of 20 cities around India on a particular day in November.

Find the range of the data.

$22,15,6,25,18,14,0,29,18,21,14,17,0,21,18,-2,17,5,11,18.$

Answer 1

Step 1: Arrange the given data in ascending order.

Given data for the temperature (in degree centigrade):

$22,15,6,25,18,14,0,29,18,21,14,17,0,21,18,-2,17,5,11,18$

Arrange the given data in ascending form,

$-2,0,0,5,6,11,14,14,15,17,17,18,18,18,18,21,21,22,25,29$

Step 2: Find the range of given data.

Maximum Temperature $=29$

Minimum Temperature $=-2$

We know that Range = Maximum value $-$ Minimum value

$\therefore$ Range $=29-(-2)=29+2=31$

Hence, the range of the given data is $31$.
