Solve this:
Answer and get 500 points
Frequency
The class (40-60) has the maximum
frequency; therefore this is the modal class.
Lower limit of the modal class
40
Width of the class interval h= 20
Frequency of the modal class h = 18
Frequency of the class preceding the modal
class fk-l = 6
Frequency of the class succeeding the modal
class fk+l = 10
Now, we have the following formula to find the
value of mode.
Mode = + h
18-6
= 40+20 x
= 40 + 2
= 42
Hence the value of mode is 42.
