ANOVA can be a very useful tool and is one of the more powerful statistical techniques for comparing dependent variable outcomes.We have discussed single and two group hypothesis testing.When there are multiple groups you use Analysis of Variance.It is also used in regression modeling.

Think up a question that you might encounter at your workplace (or elsewhere, if you are so inclined) that would be amenable to testing via ANOVA.Post that question along with any issues you think you might encounter should you actually run the analysis, including how you might get the data, sampling issues, etc.
