The image describing Tukey's box/violin plots has some factual errors. I am referring to the image at http://matplotlib.org/_images/boxplot_explanation.png, shown on http://matplotlib.org/faq/howto_faq.html#interpreting-box-plots-and-violin-plots.

• The text for Q3 should read "Third Quatrile (threshold so that 75% of the data points fall below Q3)". ("above" -> "below")
• Outlier description should read "value < Q1 - 1.5 x IQR or value > Q3 + 1.5 x IQR". ("Q3 +" -> "Q3 -", and the inequality needs to be split up.)
