Question 149

The median of the following data is
28, 4, 21, 42, 10, 9, 24, 30, 16, 5, 13

Solution

Data Set: 28, 4, 21, 42, 10, 9, 24, 30, 16, 5, 13

To find median, we first need to sort them in ascending order,

4,5,9,10,13,16,21,24,28,30,42

No, of terms,n= 11,

So median = $$\left(\ \frac{n+1}{2}\right)\ term\ if\ n\ is\ odd$$

= $$\left(\ \frac{11+1}{2}\right)\ =\ \frac{12}{2\ }\ =\ 6th\ term$$
