Box/Whisker plot

Box/Whisker plot icon

Display the distribution of numeric data through their quartiles by creating a Box & Whisker plot. Add a categorical variable to compare the data within each category.

Details

Box and Whisker Plots display a 5 number summary of the data distribution. The values included in the summary are minimum, maximum, Q1, Q3 and the median.

The lines, known as the whiskers, extending out from the boxes show the variation outside of the quartiles. Run the Box and Whisker module by selecting a numerical variable (y). To further your plot, select a categorical group variable (group) to show the data distribution per each category.
