在SPSS里选择Analyse--Nonparametic--K-Independent Samples，将第一列输到Test Variables里，第二列输到Grouping Variables，点击Define Range，定义1和3，点击OK就可以了

能说明理由么？兄弟

NPAR TESTS K-W=varlist BY variable(1,3)

K-W (alias KRUSKAL-WALLIS) tests whether k independent samples defined by a grouping
variable are from the same population. The output shows the number of valid cases and the
mean rank of the variable in each group in the Ranks table and the chi-square, degrees of
freedom, and probability in the Test Statistics table.
