Box Plot

Also known as a box-and-whisker plot, this chart allows a user to see the distribution of values across an axis. The box in the middle highlights 50% of the data, split into two with the high and low parts. The ‘whiskers’ extend to the smallest and largest data points that are within 1.5 times the interquartile range (IQR) from the lower and upper quartiles, respectively. In some variations, the whiskers extend to the actual minimum and maximum values in the dataset.
