What you’ll learn to do: Understand how to conduct a one-way ANOVA and what the conclusion means

Teachers report that they typically spend between $300 and $1000 out of their own pocket on supplies for their classrooms. Do teachers from different states spend the same amount of money on average on supplies for their classrooms? If we looked at samples of teachers from all 50 states, the degrees of freedom would be larger than if we only looked at samples of teachers from 10 states. The degrees of freedom is a characteristic that impacts the shape of an F-distribution.
