In these worksheets, students will learn how to draw stem and leaf plots. They will then use the plots that they have drawn to answer questions. These worksheets explain how to read and interpret simple stem and leaf data tables. It also includes ample worksheets for students to practice independently. This worksheet explains how to use these types of plots to find the median and the mode.

## 6.4: Stem and Leaf Plots

Histograms are one of the most widely used methods for displaying the observed values for a variable. However, they do take a little bit of effort to draw. Sometimes it can be quite useful to make use of simpler, if less visually appealing, options. One such alternative is the stem and leaf plot. To a first approximation you can think of a stem and leaf plot as a kind of text-based histogram. With all that as background, lets have a look at stem and leaf plots.

The AFL margins data contains observations, which is at the upper end for what you can realistically plot this way.

The function in R for drawing stem and leaf plots is called stem and if we ask for a stem and leaf plot of the afl. The values to the left of the are called stems and the values to the right are called leaves. If you just look at the shape that the leaves make, you can see something that looks a lot like a histogram made out of numbers, just rotated by 90 degrees.

Hm… 11 6 versus Obviously the stem and leaf plot is trying to tell us that the largest value in the data set is Similarly, when we look at the line that reads 10 , the way we interpret it to note that the stem and leaf plot is telling us that the data set contains observations with values , and Finally, when we see something like 5 the four 0 s in the the stem and leaf plot are telling us that there are four observations with value The two arguments that you can use to do this are:.

Try the following two commands to see what happens:. The only other thing to note about stem and leaf plots is the line in which R tells you where the decimal point is.

If our data set had included only the numbers. If you want to see this in action, try the following command:. The stem and leaf plot itself will look identical to the original one we drew, except for the fact that R will tell you that the decimal point has moved.

Abstract This lesson is designed to introduce students to stem-and-leaf plots. Objectives Upon completion of this lesson, students will: have been introduced to the notion of stem-and-leaf plots. Standards The activities and discussions in this lesson address the following NCTM standards : Data Analysis and Probability Formulate questions that can be addressed with data and collect, organize, and display relevant data to answer them select, create, and use appropriate graphical representations of data, including histograms, box plots, and scatterplots Select and use appropriate statistical methods to analyze data find, use, and interpret measures of center and spread, including mean and interquartile range discuss and understand the correspondence between data sets and their graphical representations, especially histograms, stem-and-leaf plots, box plots, and scatterplots Links to other standards. If this has already been covered, ask the class to recall what was learned about the topics. Objectives Let the students know what they will be doing and learning today. Say something like this: Today, class, we will be talking about stem-and-leaf plots, which are used to help us statistically analyze sets of data.

## Stem-and-Leaf Plots Worksheets

One simple graph, the stem-and-leaf graph or stemplot , comes from the field of exploratory data analysis. It is a good choice when the data sets are small. To create the plot, divide each observation of data into a stem and a leaf.
