Question 85686

           Mean = sum of all the terms/ number of terms
                =($25+$75+$156+$215+$318)/5
                = (789)/5
                = 157.8
          Median= (n+1)/2   term
                =(5+1)/2 term
                = 6/2  term
                = 3rd term
            therefore Median = 156    (arrange the terms in the ascending order
                                           and then choose the third term)
