This is the person example of a Analysis of Variance

A potential example of an "Analysis of Variance" that could be conducted within the social sciences is the effects of caffeine on exam taking. Rather than just comparing no caffeine vs. caffeine, this hypothesis would investigate three different levels of this variable: no caffeine use, coffee as a source of caffeine, and an energy drink (Celcius) as a different source of caffeine. Conducting an ANOVA involves two main steps. A general test would be one of the procedures used to see if there are any mean differences between these three groups when taking the exam. To determine precisely where there are group differences, a post-hoc test will be performed. I believe the null hypothesis for this study would be that whether a student consumed coffee, energy drinks, or none at all, there would be no difference in how well they performed on the exam. The alternative hypothesis for this study is that whether or not a student consumed any caffeine, coffee, or an energy drink would show a difference in how well they performed on the exam. I believe this hypothesis' data would support the notion that students do better on examinations when they have a caffeine source of coffee before the exam.
