In descriptive statistics, a box plot or boxplot is a method for graphically depicting groups of numerical data through their quartiles. Box plots may also have lines extending vertically from the boxes indicating variability outside the upper and lower quartiles, hence the terms box-and-whisker plot and box-and-whisker diagram. Outliers may be plotted as individual points. Box plots are non-parametric: they display variation in samples of a statistical population without making any assumptions
In a box and whisker plot: the ends of the box are the upper and lower quartiles, so the box spans the interquartile range; the median is marked by a vertical line inside the box; the whiskers are the two lines outside the box that extend to the highest and lowest observations. Example 1 â Box and whisker plots Summary A box and whisker plot (sometimes called a boxplot) is a graph that presents information from a five-number summary. It does not show a distribution in as much detail as a stem and leaf plot or histogram does, but is especially useful for indicating whether a distribution is skewed and whether there are potential unusual observations in the data set.
