Fractile Graphical Analysis is a new method of statistical analysis which provides an effective summary of information particularly useful in situations where the data do not permit a description in terms of a few parameters relating to the distribution; it also provides a graphical way of testing differences between groups. This method can be used for any variate which can be ranked. In this paper, the use of this method is illustrated for the comparison of economic data--relating either to the same population at different points of time or to different populations--by means of examples taken from the Indian National Sample Survey.
