    If we are comparing the result of more than two different process and ANOVA shows that p value is less than 0.05 implying that the three processes are statistically different, how do we check exactly which processes are different and which ones are same

    Use turkey test. U could use this function in minitab. It would compare each pair and give u back the P value.

    Gary,
    It’s still 6 months until Thanksgiving, so I would think he might want to use Tukey’s test.
    No p value, but a confidence interval.

    It’s called pairwise comparison of means.  See the post below.
