The given distrib
Lets plot a graph of ‘less than ogive’, taking upper limits of the class intervals on x - axis and cumulative frequencies on y - axis.
As we have N = 80 by the frequency table.
N/2 = 80/2 = 40
Mark 40 on y - axis and the corresponding point on x - axis would be the median.
The corresponding point on x - axis is 76.
Hence, median is 76.
