Overview for Boxplot

Use Boxplot to assess and compare the shape, central tendency, and variability of sample distributions and to look for outliers. A boxplot works best when the sample size is at least 20. A boxplot shows the median, interquartile range, range, and outliers for each group. The following boxplot represents the heights of plants grown with two different fertilizers and no fertilizer (control).
