Examples of ANOVA use
Analysis of variance (ANOVA) is used to determine if there is a difference between the means of different populations. For example, I had a student in Prescott who raised hens. A company was trying to sell her the feed they produced by claiming that if her hens ate their feed the hens would produce more eggs. They offered her a study to read in which they demonstrated that their feed was the best. To support this they conducted an experiment in which they fed four different types of food, including their own, to groups of hens. They wanted to show that on average hens that ate their food produced more eggs. They used analysis of variance. This is a true story. Can you think of examples at work in which ANOVA is used or could be used?
