Purplemath The following examples provide some practice with stem-and-leaf plots, as well as explaining some details of formatting, and showing how to create a "key" for your plot. Subjects in a psychological study were timed while completing a certain task. Complete a stem-and-leaf plot ...
A stem-and-leaf plot (or simply stemplot), was invented by John Tukey (The idea behind the stemplot can be traced back to the work of Arthur Bowley in the early 1900s.) in his paper "Some Graphic and Semigraphic Displays" in 1972. It is a valuable tool in exploratory data analysis...

Purplemath 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 ...
The stem and leaf plot calculator helps you to generate a stem-and-leaf display for a given set of integers. Read on to know more about what a stem-and-leaf plot is, how to interpret the stem-and-leaf plot, and how to calculate the median from the stem-and-leaf plot. Furthermore,...
Students create, read and analyze stem and leaf plots. Data is decomposed into "stems" and single-digit "leaves"; the resulting plot both concisely lists all the data points and creates a visual representation of the data distribution. Make: Worksheet #1 Worksheet #2 Worksheet #3 Read: Work...
