The chart displays the age breakdown of a small population.

Stem and Leaf Plots. A Stem and Leaf Plot is a special table where each data value is split into a "stem" (the first digit or digits) and a "leaf" (usually the last digit). Like in this example: Example: "32" is split into "3" (stem) and "2" (leaf). More Examples: Stem "1" Leaf "5" means 15; A stem-and-leaf diagram, also called a stem-and-leaf plot, is a diagram that quickly summarizes data while maintaining the individual data points. In such a diagram, the "stem" is a column of the unique elements of data after removing the last digit. The final digits ("leaves") of each column are then placed in a row next to the appropriate column and sorted in numerical order.

Stem-and-leaf plots are a method for showing the frequency with which certain classes of values occur. You could make a frequency distribution table or a histogram for the values, or you can use a stem-and-leaf plot and let the numbers themselves to show pretty much the same information.

A Stem and Leaf Diagram, also called Stem and Leaf plot in R, is a special table where each numeric value split into a stem (First digit(s) ) and a leaf (last Digit). For example, 57 split into 5 as stem and 7 as a leaf. In this article, we show you how to make a Stem and Leaf plot in R Programming language with example. ...
