Question

Listed below are the temperatures in $°C$ for $10$ days.

$–6,–8,0,3,2,0,1,5,4,4$

What is the range of the data?

Answer 1

Step 1: Calculate the maximum and minimum observation

It is given that the temperatures in $°C$ for $10$ days are,

$–6,–8,0,3,2,0,1,5,4,4$

Arranging the above data in ascending order,

$-8,-6,0,0,1,2,3,4,4,5$

Here, the maximum observation $=5°C$

And, the minimum observation $=-8°C$

Step 2: Calculate the range of data

As we know that,

Range of data $=$ maximum observation $-$ minimum observation

$\Rightarrow$ Range of data $=5°C-\left(-8°C\right)$

$\Rightarrow$ Range of data $=5°C+8°C$

$\Rightarrow$ Range of data $=13°C$

Hence, the required range of given data is $13°C$.
