For the following
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 = 100 by the frequency table.
N/2 = 100/2 = 50
Mark 50 on y - axis and the corresponding point on x - axis would be the median.
The corresponding point on x - axis is 55.
Hence, median is 55.
