What is an individual value plot?

An individual value plot is a graph that you can use to examine the individual values in each sample to and assess sample distributions, with optional grouping by categorical variables. An individual value plot also helps you look for obvious data entry mistakes.

The individual value plot, like a boxplot, helps you identify outliers and distribution shape, but it is unique in that it graphs each value separately. This is especially useful when you have relatively few observations.

This individual value plot compares the elasticity of rubber bands made during three consecutive weeks. While the mean elasticity increases over time, the variation (the spread of the points in each group) increases dramatically in the third group.
