MCQ

Choose the correct answer from the given four options:
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
✓
20
D
38

✓

Answer

Correct option: C.

20

Here,

Class	Frequency	Cumulative frequency
65-85	4	4
85-105	5	9
105-125	13	22
125-145	20	42
145-165	14	56
165-185	7	63
185-205	4	67

Here, $\frac{\text{N}}{2}=\frac{67}{2}=33.5$ which lies in the interval 125-145.
ence, upper limit of median class is 145.
Here, we see that the highest frequency is 20 which lies in 125-145. Hence, the lower limit of modal class is 125.
Required difference = Upper limit of median class - Lower limit of modal class = 145 - 125 = 20
