Let's use ANOVA for a real life situation. Try the Virtual Online Catapult. http://sigmazone.com/SL/Catapult/
Set up an Anova method Explain the design you chose, what was conducted, and the results obtained from the experiment.
What pitfalls or trouble was found while in the design process, experimental run, or analyzing the results?
Discussion 16
Analysis of Variance has been a central pillar of statistical thinking and practice for at least 70 years.
Given its lengthy history, ANOVA has received some criticism. Other statistical techniques are preferred. Advances in computational techniques have also altered the favor of using ANOVA for experimental designs.
Discuss some advantages and/or disadvantages of ANOVA. If ANOVA is not the preferred method, what method of design is recommended and why?
