Week 6 Discussion:
Analysis of Variance
This week, we are
studying Analysis of Variance, commonly called ANOVA. ANOVA is used the compare
the mean of a dependent variable associated with the effect of at least three
independent variables. For example, we could study the mean sodium amount in condiments,
desserts, and cereal. In this case, the dependent variable is the amount of
sodium and the independent variables are condiments, desserts, and cereal.
Note: The hypothesis test using ANOVA will tell you if the mean is the
same for the samples but does not tell you which is different.
