1. Stem & Leaf Plots

2. Stem & Leaf Plots Stem and Leaf plots are a way of organizing
(This is clip art.)
Stem and Leaf plots are a way of organizing
a wide range of numbers in a set of data.

3. (1’s) 7 9 12 3 5 8 5 7 6 8 9 (100’s,10’s) In a stem & leaf plot,
Number of Books per Classroom
(100’s,10’s)
(1’s) 7 9 12
5 7
In a stem & leaf plot,
the digit or digits in the left “stem” column
are combined with a single digit in the right “leaf” column
to form a numeral.

4. Place 7 (the digit in 10’s place) in the stem column.
For example, to plot the number 75,
Place 7 (the digit in 10’s place) in the stem column.
Place 5 (the digit in 1’s place) in the leaf column.

5. Place 27 (the digits in 100’s and 10s place) in the stem column.
To plot a 3 digit number such as 275,
Place 27 (the digits in 100’s and 10s place) in the stem column.
Place 5 (the digit in 1’s place) in the leaf column.

6. Here is an example: (1’s) 2 15 5 6 7 7 2 3 (100’s,10’s)
Number of Candy Bars Sold per Student
(100’s,10’s)
(1’s) 2 15

This plot shows this set of data: (25, 26, 27, 27, 152, 153)

7. 6 1 5 8 7 2 5 8 0 2 2 9 3 10 2 3 7 11 8 9 Here is another example:
Number of Students per Year
(100, 10’s) (1’s) 6 7
2 5 8 9 3 10 11
8 9
The numbers plotted above are:
61, 65, 68, 72, 75, 80, 82, 82, 93, 102, 103, 107, 118, 119

8. B A B A How do you plot the number 315 ? (1’s) 31 5 (10’s, 1’s) 3 15
