Correct Answer – Option 2 : 7
Concept:
Median: It is the middle value in the given set, while the set is either in increasing or decreasing order.
If the number of observation (n) is odd then median is (n+1)/2th term.
If the number of observation (n) is even then the median is average of nth and (n+1)th term.
Calculation:
Given observation are 5, 6, 11, 23, 4, 8, 20, 2
Increasing order of given data: 2, 4, 5, 6, 8, 11, 20, 23.
The number of observation is even. (n = 8)
So, the median is theaverage of nth and (n+1)th term or average of 4th and 5th term
Median \(= \frac{6+8}{2}\)
= 7
