find the median of the following data :
x- 10,20,30,40,50
f- 2,3,2,3,1
UnknownDude:
Total f = 11
11/2 = 6.5
6.5 lies between CF = 5 and CF = 7 for class 20 and 30
So median = 30
11/2 = 5.5
Oh right, my bad
But the answer is still the same

Answer:
Step-by-step explanation:
Given x and the frequency we need to get the cumulative frequencies.
The cumulative frequencies are given as follows:
Cumulative frequency : 2 , 5, 7, 10, 11
Since the data is odd the median term is given by:
(n + 1)/2 term
In this case n = Total frequency
(11 + 1)/2 = 6
6 lies within 7 hence the median is 30.
The median of the given data is therefore 30.
