Draw 'less than ogive' and 'more than ogive' on a single graph paper and hence find the median of the following data:
Answer :
The frequency distribution table for ‘less than’ type is:
The frequency distribution table for ‘more than’ type is:
Plotting points for ‘less - than ogive’ and ‘more - than ogive’ on the graph,
In this type of graph where ‘less than ogive’ and more than ogive’ are plotted in the same graph, median is found on x - axis by the intersection of these two ogives.
Here, median = 15.5
