For the following distribution draw a 'less than type' ogive and from the curve find the median.

Answer :

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.
