Question

4. Find the range and mean of the following data :
2,3,3,4,5,2,3,4,5​

Answer 1

range =maximum number-minimum number

=5-2

=3

mean =sum of all observations/number of observation

=2+3+3+4+5+2+3+4+5/9

=21/9

=7/3

Answer 2

Answer:

Range of the data = 3

and mean of the data = 3.44                  

Given data:

Find the range and mean of the following data :  2,3,3,4,5,2,3,4,5​

Step-by-step explanation:  

Given data:   2, 3, 3, 4, 5, 2, 3, 4, 5​  

rewrite the given data in ascending order

⇒   2, 2, 3, 3, 3, 4, 4, 5, 5  

number of observation in given data = 9  

Range of the data = largest vale - smallest value

                               = 5 - 2 = 3

Mean of the data = sum of observation / number of observations

                              =  $\frac{2+2+3+3+3+4+4+5+5}{9}$  

                              = $\frac{31}{9}$   = 3.44
