The median of a given frequency distribution is found graphically with the help of
A. Histogram

B. Frequency curve

C. Frequency polygon

D. Ogive

Answer :

There are two ways in which median can be determined graphically.

(1) By drawing any of the ogive

In this case, we first compute , where N is the sum of frequencies and then we locate the point M corresponding to Nth cumulative frequency on curve, and the x-coordinate of M gives the median.

(2) By drawing both of the ogives

We draw both ogive curves [i.e. less than ogive and greater than ogive] and intersection of both ogives gives the value of median.
