The graphical method for finding the medain is
By constructing less and greater than cumulative frequencies
By plotting on graph we obtain an ogive curve and intersection of those two curves then we obatain median.
So the graphical method for finding median is ogives.
Numerical method :
Arrange the data either in ascending order or descending order then select the middle value as the median.

Question 1: (24 marks)

shares provide just such a hedge against inflation. The annual
Australian inflation rate (as measured by percentage changes in the
consumer price index) and the annual All-Ordinaries Index from 1995
to 2015 are stored in file INFLATION.XLSX.
