A stem and Leaf Plot is way to display quantitative data in a graphical format, where it refers to plotting a matrix of y values onto an x-axis, identifying the common x value with a vertical line and the individual y values with symbols on the line. A basic display of a stem and leaf plot contains two columns separated by a vertical line. The left column contains the stems and the right column contains the leaves. Typically, the leaf contains the last digit of the number and the stem contains the rest of the digits. The above image is a stem and leaf plot of infant mortality rates in Western Africa. Here, you can clearly see how the plot is divided into two columns, with the stems on the left column and the leafs on the right column.
