Box & Whisker Plot

The Box & Whisker Plot, or Box Plot, widget is a convenient way of visually describing the distribution, variability, and center of a data set along an axis.

Box Plots are divided into four quartiles. The middle quartiles are represented by a box that contains 50% of the data and the median value. The upper and lower quartiles contain the maximum and minimum values and the remaining 50% of the data. These quartiles are represented by lines called whiskers.

The maximum and minimum values can be adjusted when defining your box plot. By default, these values are within 1.5 times of the IQR (Interquartile Range), however you can set them to the actual maximum and minimum values or to within one standard deviation of the mean of your data.

Box plots divide five descriptive statistics into four equal quartiles. You can view these statistics by hovering over the Box Plot.
