Then the last digit in 60 will match up with the stem 6. The last digit in 57 will match up with the stem 5.

Create the stem by listing numbers from 5-9. ![]() Then the last digit in 85 will match up with the stem 8 and this pattern will continue until all data have been recorded in the stem-and-leaf. ![]() Then the last digit in 79 will match up with the stem 7. The last digit in 76 will match up with the stem 7. 3 0 5 6 7 8 9 7 7 8 6 9 5 5 2 0 0 3 Rearrange the leaf in numerical order from least to greatest 5 2 1 3 1 0 2 5 5 6 9 7 4 2 8 1 1 2 3 5 Key: 79 means 79 2 4 7 8 Match up the data to the stem-and-leaf. Stem Leaf 5 6 7 8 9 8 8 7 Stem Leaf A key should be included when making a stem-and-leaf plot. ![]() Statistics: Stem-and-Leaf Plots Here are the scores from two periods of math class. The stem with the leaf forms the number 284. The stem is the remaining digits when the leaf is dropped: the number 28. Look at the number 284 The leaf is the last digit formed: the number 4. Stem: The digit or digits that remain when the leaf is dropped. Statistics: Stem-and-Leaf Plots Leaf: The last digit on the right of the number. The numbers in the next greatest place-value position are then used to form the leaves.In a stem-and leaf plot, the greatest common place value of the data is used to form stems.Stem-and-Leaf Plots: A convenient method to display every piece of data by showing the digits of each number.Data: Numerical facts or numerical information.Statistics: The branch of mathematics that deals with collecting, organizing, and analyzing or interpreting data.Statistics: Stem-and-Leaf Plots Week of 4/11/11 Day 3 Sometimes the stem is the ones place and the leaf is the tenths place Data points are: 2.2, 2.4, 2.5, 2.8 3, 3.1, 3.3 4.6, 4.7 5.3, 5.5, 5.- E N D - Presentation Transcript.(tens) (ones) 4 7 Remember: This represents 47 47 Mode = _ The mode is the value(s) that occurs most often.If crossing out the leaves confuses you, list the data points out first and then cross them off 22, 24, 25, 28, 30, 31, 33, 46, 47, 53, 55, 55 (tens) (ones) 31 + 33 = 64 64 ÷ 2 = 32 32 Median = _.If there are 2 middle values, take the average of the 2.Cross out the smallest and highest leaves together until you find the middle value.Minimum, Maximum, Range minimum point (tens) (ones) Combine the tens and ones 20 + 2 = 22 maximum point Combine the tens and ones 50 + 5 = 55 22 55 33 Minimum = _ Maximum = _ Range = _ (55 – 22) Put the following values into a stem and leaf plot.There are 12 leaves, so you have 12 data points.If you count the leaves, you will know how many data points there are.The stems represent the tens digit and the leaves represent the ones Data points are: (tens) (ones) 22, 24, 25, 28 30, 31, 33 46, 47 53, 55, 55.Stem and Leaf Plots emphasize place value.
