Stem-and-Leaf Plots

How to Read Them and Construct Them


A stem-and-Leaf Plot The data is arranged by place value. The digits in the largest place is referred to as the stem and the digits in the smallest place are referred to as the leaf (leaves). The leaves are always displayed to the right of the stem. They are usually used when there are large amounts of numbers to analyze, such as series of scores in sports

Stem-and-Leaf Plot

In this case, the stem is the tens digit of the numbers and the leaf is

the ones digit.

Example: The stem and leaf plot below represent the following set

of numbers:

0,0,4,6,6,7,9,9,10,11,12,13,14,15,18,19,21,22,23,26,35

In this case, the stem is the tens digit of the numbers and the leaf is

the ones digit.

Example 2 TEST SCORESThe table below shows the test scores earned by a class of middle school math students on a chapter test. Make a stem-and-leaf plot of the data. Then use it to describe how the data are spread out.
