A stem-and-leaf plot is a method for organizing and displaying numerical data, where each data point is divided into two components: a stem, which consists of the leading digit or digits, and a leaf, the trailing digit. In this plot, the stems are typically listed in a column, with the leaves fanned out to the right. The leaves are sequenced next to their corresponding stems, following a numerical progression from smaller to larger values.

The scores are ordered.

A
