Stem and leaf plots
A stem and leaf plot displays numerical data by splitting each data point into a "leaf" (usually the last digit) and a "stem" (the leading digit or digits).
For example, the buyer for a chain of department stores counted the number of pairs of boots at each of the stores and made a stem and leaf plot for the data. Here is the dataset and the stem and leaf plot:

Creating a stem and leaf plot
Here's how to make a stem and leaf plot step by step. We'll use the same dataset as before. Here it is again:
Step 1: Split each data point into a stem and a leaf. The stem is everything before the final digit, and the leaf is the final digit. Write the stems in a vertical column and don't skip stems just because they don't have any data.
Our are the tens digits:
Step 2: Write each leaf next to its corresponding stem. The
Step 3: Give a key that explains what a stem and leaf represent.
