Question

10. Calculate median for the following frequency distribution
class -interval 0-5 5-10 10-15
frequency 10 15
12
20-25
9
15-20
20
​

Answer 1

Step-by-step explanation:

CI frequency CF(Cummulative frequency)

0 - 5 10 10

5 -10 15 25

10 - 15 12 37

15 -20 20 57

20 -.25 9 66

As N=66 which is even

so we will use

Median = N/2

=66/2 =33
