Consider the data:
Class 65-85 85-105 105-125 125-145 145-165 165-185 185-205
Frequency 4 5 13 20 14 7 4
The difference of the upper limit of the median class and the lower limit of the modal class is
a. 0
b. 19
c. 20
d. 38

Solution:

The cumulative frequency table is

We know that

N/2 = 67/2 = 33.5

So the median class=125-145

The upper limit is 145

Here is modal class is the class with maximum frequency

Modal class is 125-145

The lower limit is 125

Difference of upper and lower limit = 145 - 125 = 20

Therefore, the difference between the upper limit of the median class and the lower limit of the modal class is 20.
