Question

find the median class of following distribution interval 0-10,10-20,20-30,-30-40,40-50,50-60,60-70 frequecy 4,4,8,10,12,8,4​

Answer 1

Answer:

To find the median class:

First add the total number of frequencies.

Here, f=50

Formula to obtain the median class =

2(Total number of frequency + 1)

So, Median class =(50+1)/2=25.5

Hence, the median class of 25.5 lies between the intervals 20−30.
