Question

In the given frequency distribution table the median class is :

Class Interval Frequency
0-10 5
10-20 8
20-30 12
30-40 15
40-50 20


A. 10-20 B. 20-30
C. 30-40 D. 0-10​

Answer 1

Answer:

Correct option is

B 20-30

Class Frequency Cumulative Frequency

0-10 12 12

10-20 13 25

20-30 25 50

30-40 20 60

40-50 10 70

Now

N/2

=35. Hence cumulative frequency just greater than 35 is 50. The corresponding class is 20−30.
