Question

The median series is 10. two additional observation 7 and 20 are added to the series , the median of the new series is ?

Answer 1

median of a number is the middlemost no when arranged in ascending or descending order.......
since 7 is less than 10 and 20 is more than 10
so the middlemost no will remain unchanged as 1 no. is added to left and another to right.
so median is still 10.
