The median of 11, 13, 10, 9, 8, 20, 13 is:

Given:  

To find: media of 11, 13, 10, 9, 8, 20, 13.

Concept Used: 

For ungrouped data median

For odd number of term = $$\frac{(n+1)^{th}}{2} \, term$$ 

Solution: 

given set = 8, 9, 10 , 11, 13, 13, 20 

Total number of terms = 7 (odd)

Median = $$\frac{ (7 +1)^{th}}{2} = 4^{th} \, term$$ 

Thus, the median of the data is 11.
