For the following distribution:
Class 0-5 5-10 10-15 15-20 20-25
Frequency 10 15 12 20 9
the sum of lower limits of the median class and modal class is
a. 15
b. 25
c. 30
d. 35

Solution:

We know that

N/2 = 66/2 = 33 that lies in the interval 10-15

10 is the lower limit of the median class

20 is the highest frequency that lies between the interval 15-20

So the lower limit of modal class is 15

Required sum = 10 + 15 = 25

Therefore, the sum of lower limits of the median class and modal class is 25.
