Box & Whisker plots make use of the five-way summary (median, lower quartile, higher quartile, minimum, and maximum) when describing data. Some other methods that require calculation include a histogram, which needs a class interval and a pie chart that requires one to calculate the degree of each slice in the pie.Ĭomputations are no doubt a common occurrence in statistical analysis, but minimal when visualizing data. Box & Whisker plot is one of the few data visualization techniques that perform further computations on the dataset before it can be visualized.
