Introduction
The median test is a statistical procedure for testing whether two
independent populations differ in their measure of central tendency
or location. That is median test enables us determine, whether it is
likely that two independent or unrelated samples not necessarily of the
same size have been drawn from two populations with equal medians.
The median test may be used whenever the observations or scores
obtained from the two populations are at least on the ordinal scale
of measurement. In these situations, the assumptions of normality
and homogeneity necessary for the valid use of the parametric ’t’ test
may not be satisfied so that parametric tests may not here readily
recommend themselves [1]
