MCQ

Consider the following frequency distribution:

Class:	0-5	6-11	12-17	18-23	24-29
Frequency:	13	10	15	8	11

The upper limit of the median class is:

A
17
✓
17.5
C
18
D
18.5

✓

Answer

Correct option: B.

17.5

Given, classes are not continuous, so we make continuous by subtracting 0.5 from lower limit and adding 0.5 to upper limit of each class.

Class	Frequency	Cumulative Frequency
0.5-5.5	13	13
5.5-11.5	10	23
11.5-17.5	15	38
17.5-23.5	8	46
23.5-29.5	11	57

Here,$\frac{\text{N}}{2}=\frac{57}{2}=28.5,$ which lies in the interval 11.5-17.5.
Hence, the upper limit is 17.5.
