Answer 1

Answer:

Range of given data is $18$ .

Step-by-step explanation:

To find : range of given data.

Given data : $10, 5, 12, 2, 15, 20, 8, 10$

Solution:

• According to question we are asked to find range of given data.
• We arrange given data in ascending order, that is from smaller to bigger number.
• Ascending order : $2, 5, 8 , 10 , 10 , 12, 15 , 20$
• Range is the difference between the highest value and lowest value of the data.
• Here, highest value $=20$  and lowest value $=2$
• Range = highest value - lowest value
• Range $= 20 - 2$  

                    $= 18$
