Question

Find the range from these following observations ( 7,5,9,12,2,89, 54,36,43,90,25,33,49 )​

Answer 1

Answer:

Range of given observation is $88$ .

Step-by-step explanation:

To find : range of given data .

Given data : $( 7,5,9,12,2,89, 54,36,43,90,25,33,49 )$

Solution :

• In question we are asked to find the range of given data .
• Therefore ,to find range we first arrange observations in ascending

        order : $2, 5,7,9,12,25,33,36,43,49,54,89,90$ .

• Range is the difference between highest value and smallest of observation .
• Formula :

       Range = highest value - smallest value

• Here , highest value = $90$  and smallest value = $2$
• Therefore ,  Range = $90 -2$

                                        $= 88$
