Comparing Distributions of Univariate Data

When comparing distributions of univariate data, graphs can be used to describe differences in center, spread, clusters in the data, gaps in the data, outliers, unusual features, and shape of the distribution.
Common graphs are stacked dotplots, stemplots, and boxplots.
