1. 5.8 Stem-and-Leaf Plots Standards: SDP 1.1, SDP 1.3 Objective: Use stem-and-leaf plots and back-to-back stem-and-leaf plots

2. Stem-and-Leaf Plot A display of data that allows you to see the way the data are distributed. It places data in increasing or decreasing order.

3. Stem-and-Leaf Plot 1 1 2 7 9 29 3 0 3 5 8 4 1 2 6 7 5 4 5 7 8 In the first group, you have 11, 12, 17, 19 In the first group, you have 11, 12, 17, 19 Second stem, you have 29 Second stem, you have 29 Third stem, you have 30, 33, 35, 38 Third stem, you have 30, 33, 35, 38 Fourth Stem, you have 41, 42, 46, 47 Fourth Stem, you have 41, 42, 46, 47 Fifth stem, you have 54,55,57,58 Fifth stem, you have 54,55,57,58 The STEM is the first part of the number, in this case it is the tens digit. The LEAF is the second part of the number, in this case it is the ones digit. Stem-and-leaf plots are good for making lists of numbers shorter and more organized.

4. You try a stem-and-leaf plot. Step 1: Order the Numbers from Least to greatest. Step 2: Decide what Your stems will be. Step 3: Add the Leaves in order from Least to greatest. Step 4: Include a Key to explain what The stem stands for And the leaf stands For.

5. Answer to the stem-and-leaf plot. Step 1: Order the Numbers from Least to greatest. Step 2: Decide what Your stems will be. Step 3: Add the Leaves in order from Least to greatest. Step 4: Include a Key to explain what The stem stands for And the leaf stands For.

6. Back-to-back Stem-and-Leaf Plot A back-to-back plots helps compare two sets of data. A back-to-back plots helps compare two sets of data. Write one set of leaves on the left side of the stem, and one set of leaves on the right side of the stem. Write one set of leaves on the left side of the stem, and one set of leaves on the right side of the stem. 010 1 1 2 9 5 2 11 4 6 9 8 5 3 12 4 5 5 7 7 1 13 9 9
