Each lesson involves creating, by hand or with a graphing calculator, appropriate graphical displays based on real-world data. The specific advantage of the stem-and-leaf plot over a histogram is that the stem-and-leaf plot, aside from showing the distributional properties. Next, enter the data from the stem and leaf in column L1 on your calculator by going to STAT, then #1 Edit. The ranges are represented, but so are the exact values.

The following link to 'Statistics Canada' gives an overview of the features of a stem and leaf plot, and how they are constructed and interpreted. A stem-and-leaf plot is a chart tool that has a similar purpose as the histogram, and it is used to quickly assess distributional properties of a sample (the shape of its probability distribution). The stem of a number is the digit or digits on the left side of the number, and the leaf of a number is the final right-hand digit. Round or truncate your values if necessary. Hello!
