×h
Where ,
I= lower limit of the modal class =40
f

= frequency of modal class =12
f
2
frequency of class after the modal class =6
f
0
frequency of class before the modal class =10
h= class width =20
putting the values in the equation
Mode=50

Mean:
10+12+25+30+14
=91
91÷5= 18.2
Median:
order the set of number and middel is median
10. 12. 14. 25. 30
=14
Mode:
The most common number
10. 12. 14. 25. 30
= the set of data is no mode.
hope its helpful
