2. Stem-and-Leaf Plot
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
In this case, the stem is the tens digit of the numbers and the leaf is
the ones digit. 5 3 2 1
Leaf
Stem
1|3 = 13 hours

3. 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. 5 3 2 1
Leaf
Stem
1|3 = 13 hours

4. Example 2 TEST SCORES The 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.
Test Scores
Answer: 9 8 7 6 5
