Question

8. What is the mode class of following data ?
Class
0-6 6-12 12-18 18-24 24-30
Frequency 3 2 1 14 8 1 11​

Answer 1

Answer:

The mode is basically the range that occurs the most frequently.

Step-by-step explanation:

Answer 2

The mode for the following data is 20.9.

Step-by-step explanation:

$\text {Mode }(Z)=l_{1}+\left(\frac{f_{1}-f_{0}}{2 f_{1}-f_{0}-f_{2}}\right) \times i$    

where,

$l_1$ - Lower class of the highest frequency = 18

$f_1$ - Highest frequency of modal group = 81

$f_0$ - Frequency before the highest frequency of modal group = 14

$f_2$ - Frequency after the  highest frequency of modal group = 11

i - Class interval = 6

$\text {Mode }(Z)=18+\left(\frac{81-14}{(2 \times 81)-14-11}\right) \times 6$

                $= 18 + (\frac{67}{137} ) \times 6$                  

                = 18 + 2.93 = 20.93

The correct question is :

Class          -   0-6    6-12    12-18    18 -24    24 - 30

Frequency -     3        21         14          81           11
