In Europe, sometimes stem-and-leaf plots, like those pictured above, are used to display public transportation timetables, with the hours along the “stem” and the minutes as the “leaves.” Check out this bus schedule in Sochi, Russia. You might have to turn your head to recognize the stem-and-leaf plot.

What are stem-and-leaf plots used for?

A stem and leaf plot, or stem plot, is a technique used to classify either discrete or continuous variables. A stem and leaf plot is used to organize data as they are collected. A stem and leaf plot looks something like a bar graph. Each number in the data is broken down into a stem and a leaf, thus the name.

What is a stem-and-leaf display best used for?

The histogram and stem-and-leaf are used to graphically display quantitative data; a scatter plot is used for displaying the relationship between two variables.

What are stem plots useful for?

Stemplots are useful both for quantitative and categorical data sets. Stemplots can show symmetry, gaps, clusters, and outliers. D. Stemplots may or may not show individual values.

How does a stem plot work?

A stem and leaf plot is a way to plot data where the data is split into stems (the largest digit) and leaves (the smallest digits). The stems with the largest amount of data in the picture above are the 2 and 6 stems. The numbers are arranged by place value. The largest place-value digits are placed in the stem.

How do you interpret a stem-and-leaf plot?

Steps to Interpreting a Stem Plot The stems are on the left of the vertical line and the leaves are on the right. The stems are usually the first digit of a number. So if you have a value of 25, 2 is the stem that goes on the left of the vertical line and 5 is the leaf that goes on the right.

What do you call a stem and leaf graph?

This simplified horizontal chart is called a “Stem and Leaf Plot”, a “Stem and Leaf Diagram”, a “Stem Plot”, a “Stem and Leaf Graph”, an “S & L Plot”, or an “S & L Diagram”. This material is contained in the following Slideshare Presentation of a PowerPoint we made here at Passy World.

How are stem and leaf plots used to measure data?

Stem-and-Leaf Plots and Box-and-Whiskers Plot. One way to measure and display data is to use a stem-and-leaf plot. A stem-and-leaf plot is used to visualize data. To set up a stem-and-leaf plot we follow some simple steps.

Where are the numbers in the stem plot?

Look at the crowded rows to see where the main cluster of data. The data are clustered at 15s and 16s or from 150-169. 150 is the minimum value for row 15 to represent and 169 is the maximum value that row 16 can represent. 15 has 11 numbers in its row and 16 has 13 numbers in its row.

Are there any real life stem and leaf diagrams?

Admittedly stem and leaf diagrams are rarely used in ‘real life’. In fact the only common examples we can find are timetables, such as the Japanese train timetable shown in the picture below (more examples here ).
