The following tab
The frequency distribution table for ‘more than’ type is:
Lets plot a graph of ‘more than’ ogive, taking lower limits of the class intervals on x - axis and cumulative frequencies on y - axis.
As we have N = 102 by the frequency table.
N/2 = 102/2 = 51
Mark 51 on y - axis and the corresponding point on x - axis would be the median.
The corresponding point on x - axis is 70.5.
Hence, median is 70.5.
