Unit 6 DB: ANOVAUnit 6 DB: ANOVA

ANOVA is based on comparing the variance (or variation) between the data samples to variation within each particular sample. If the between variation is much larger than the within variation, the means of different samples will not be equal. If the between and within variations are approximately the same size, then there will be no significant difference between sample means.

Give an example of when we would use an ANOVA. Provide details of why an ANOVA is an appropriate statistical test in your example. What would your null and alternate hypothesis be for your example?
