• PARAMETRIC AND NON PARAMETRIC TEST
• IF THE INFORMATION ABOUT THE POPULATION IS COMPLETELY KNOWN BY MEANS OF ITS PARAMETER THEN STATISTICAL TEST IS CALLED PARAMETRIC TEST. PARAMETRIC OFTEN MEANS THAT A TEST ASSUMES THE TESTED VARIABLE ARE NORMALLY DISTRIBUTED. SUCH TEST OFTEN USE REGULAR NOMINAL VALUES AND AVERAGES
•  FOR EXAMPLE t-test,f-test,z-test and ANOVA
• IF THERE IS NO KNOWLEDGE ABOUT THE POPULATION OR PARAMETER BUT STILL IT IS REQUIRED TO TEST THE HYPOTHESIS OF THE POPULATION THEN IT IS CALLED NON PARAMETRIC TEST. FOR EXAMPLE MANN-WHITNEY,RANK SUM TEST,KRUSKAL-WALLIS TEST. INSTEAD OF NOMINAL VALUES . THEU LOOK AT THE DIFFERENCE IN MEDIAN INSTEAD OF AVERAGES
