Question

Find the median of: 25, 16, 26, 16, 32, 31, 19, 28 and 35

Sum

Solution

 Firstly arrange the numbers in ascending order
16, 16, 19, 25, 26, 28, 31, 32, 35

Now since
n = 9( odd )

Therefore the Median

= `(( n + 1 ) / ( 2 ))^"th"`  

= `(( 9 + 1 ) / ( 2 ))^"th"`  

= 5th

Thus the median is 26.
