Box-and-Whisker Plots




Exploring Quartiles

            Lower Quartile (Q1), Upper Quartile (Q3), Median (Q2)


And the Winner Is?—Parts 1 and 2


Modified Box Plots and Outliers

            IQR—interquartile range—range of middle 50% of the data


            Box goes from Q1 to Q3—Q2 is inside the box


            Outliers are half of a box to the left Q1 or to the right of Q3

            Whiskers do not extend to outliers
