: This paper has been used to give insight for the researches or the students of high school about nonparametric statistic and it’s applications at the analysis of simple regression specially to fit the regression line and the test of hypotheses. A regression line of estimation Y = a + bX, in nonparametric statistic a and b can be found way of manual with least square method. But in nonparametric statistic can be found way of manual with Brown-Mood method. The test of hypotheses for a and b from population with model of regression equalization Y = a + bX is used Brown-Mood method too. The statistic of test from Brown-Mood method as follow : x2 = with n, n1, and n2 follow steps from Brown-Mood.
