 Let s arrange the items in ascending order 3, 4, 6, 9,9 10, 11, 18, 22.

            In this data the number of items is n = 8, which is even.

 Median = M = average of \left ( \frac{n}{2} \right ) th and  \left ( \frac{n}{2} +1\right ) th terms.

= Average of \left ( \frac{8}{2}\right )  th and \left ( \frac{8}{2}+1\right )  th terms

     = Average of 4th and 5th terms

=\frac{9+10}{2}=\frac{19}{2}=9.5
