Use box plots, also known as box-and-whisker plots, to show the distribution of values along an axis. Boxes indicate the middle 50 percent of the data (that is, the middle two quartiles of the data's distribution). By definition, the box-plot limits the size of the whiskers to 1.5 times the interquartile range \((IQR)\) from the ends of the box (which are defined by \(Q_1\) and \(Q_3\). So, then, any points that go beyond of the maximum size of the whiskers will be annotated in the box-plot and it will be considered an outlier. Box and whisker plots are also very useful when large numbers of observations are involved and when two or more data sets are being compared. The Box and Whisker consists of two parts—the main body called the Box and the thin vertical lines coming out of the Box called Whiskers . A box and whisker plot (or box plot) is a graph that displays the data distribution by using five numbers.

The box plot is also referred to as box and whisker plot or box and whisker diagram. Elements of the box plot. The bottom side of the box represents the first quartile, and the top side, the third quartile. Therefore the vertical width of the central box represents the inter-quartile deviation.

Quantiles used are equivalent to those computed using Quantile. 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 from the boxes (whiskers) indicating variability outside the upper and lower quartiles, hence the terms box-and-whisker plot and box-and-whisker diagram. Box plots, also called box-and-whisker plots or box-whisker plots, give a good graphical image of the concentration of the data. They also show how far the extreme values are from most of the data. As mentioned previously, a box plot is constructed from five values: the minimum value, the first quartile, the median, the third quartile, and the maximum value. Use box plots, also known as box-and-whisker plots, to show the distribution of values along an axis. Boxes indicate the middle 50 percent of the data (that is, the middle two quartiles of the data's distribution).
Elements of the box plot. The bottom side of the box represents the first quartile, and the top side, the third quartile. Therefore the vertical width of the central box represents the inter-quartile deviation. The horizontal line inside the box is the median.
