Answer 1

Explanation:

For calculation of median in discrete series

1 arrange the data(n) in ascending order with their respective frequency

2 then find the cumulative frequency(cf) by adding frequency one upon one.

3 then use the last cf or total of frequency both are same and apply the formulae of median

4 then you will get the observation number and find out in what cf does the observation falls.

5 after checking and finding it out the N is the value of the median.
