The median test and its modified method is a nonparametric technique developed to handle two samples problem and their data are continuous which consist of two mutually independent random samples. In this paper, we proposed a modified median test for analyzing two sample data which helps in finding out which of the populations might have led to not rejecting the null hypothesis under consideration which is a significant improvement on the median test. It was observed using an illustrative example at 5 percent level of significance that the proposed method performed favorably well in comparison than the median test.
