The exposition on how to interpret boxplots is odd, especially the part about the difference between the median and the mean being representative of the "variance". I want to give the benefit of the doubt and assume the author is simply using "variance" to refer to a different statistical concept (e.g. skew), but then later she writes "the variance between the Washington state average & median values is negligible - meaning there is little / no variation in the dataset" which is just wrong. The WA boxplot has the largest variance of any state on the plot. And the distinction is not just academic, because that larger variance increases the potential savings for moving from their current WA home to a cheaper home in the same state.
