Median =

  Here = 30, = 35, = 250, c.f. = 150 and f = 180

Therefore, Median

Sometimes the series is given in the descending order of magnitude. In this situation convert the series in the ascending order of magnitude and then using the regular formula, the median can be calculated or the series can be put in the descending order of the magnitude and an alternative formula be used to calculate the median.
