Tujuan Kruskal Wallis adalah untuk mengetahui ada atau tidak ada perbedaan antar variabel untuk data yang tidak memenuhi syarat pengujian Anova. Hasil signifikansi p < 0, 05, maka data berbeda secara bermakna. Dilanjutkan dengan uji BNT (Beda Nyata Terkecil) menggunakan metode LSD dengan tujuan untuk menentukkan kelompok perlakuan mana yang berbeda secara bermakna dengan kelompok perlakuan lainnya.

Whether these drug treatment groups have different pain scores can be assessed using the Test Statistics table which presents the result of the Kruskal-Wallis H test. That is, the chisquared statistic (the "Chi-Square" row), the degrees of freedom (the "df" row) of the test and the statistical significance of the test (the "Asymp. Sig. " row).
