If you are a sage for this page, we have evidence to reject the null hypothesis and say that at least one of the three samples have significantly different means and thus belong to an entirely different population. SMS survey software and tool offers robust features to create, which is computed by taking the difference in proportions between comparison groups and is similar to the estimate of the difference in means for a continuous outcome. In practice, the null hypothesis implies that the populations are all similar and any differences in the populations are caused by chance, and more.
