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).
To create a boxplot, choose , then select the option that matches your data. For more information, go to Choose a boxplot.
If the sample size is less than 20, consider using Individual Value Plot.
