Performing an N-Sample Test of the Means

The OUTSTAT= output data set pvalue contains the p-value in the PROB variable. If you have multiple predictor variables, you need to use the PROC GLM ODS data set OverallANOVA to get the overall model p-value from the ProbF variable. These output data sets contain other variables, such as the degrees of freedom, sum of squares, mean square, and F statistic, if you need them for an ANOVA table presentation. 

If the populations to be compared across treatments are not normally distributed, you can use the nonparametric Kruskal-Wallis test of the distributions by running PROC NPAR1WAY as follows  

The Kruskal-Wallis p-value variable in the pvalue data set is called P KW.
