 A stem and leaf plot is a quick way to organize 25 to 100 pieces of data. Each data value is split into a stem and a leaf. Highlighted here is a stem of 7 and a leaf of 1, which means 71. We will create a stem and leaf from the above data set. The stem will be the digits in the tens place. In this case, the numbers 6 to 10. Place them in order vertically from smallest to largest. Working from left to right in the data set, place the leaves, the digits in the ones place in their corresponding row. Next, put the leaves in order in each row from smallest to largest. Be sure to include duplicate numbers. Finally, create a legend or key from your stem and leaf plot. The legend tells the reader the values of the numbers in the plot. Here 7 and 1 means 71. If you were creating a legend for this stem and leaf plot, what would a stem of 3 and a leaf of 2 mean? It means 3.2. If the stem and leaf plot is turned sideways, a histogram is created. In this histogram, all the original data is preserved. That's all there is to creating a stem and leaf plot.
