What is a Stem and Leaf Plot?

A stem and leaf plot shows the spread and distribution of a data set:

• Stems represent the first digits of the data points
• Count represents the number of data points with that first digit
• Leaves represent the second digits in the data set (numbers 0-9)
• Median is the mid point in the data set and is shown next to the leaf
