Create the stem by listing numbers from 4-6. And the median test score for period 2 is between a 73 and 75. The median score for the 20 test scores from period 1 is between a 76 and 79. Statistics: Stem-and-Leaf Plots Additional numerical facts indicate that the lowest grade in both classes was a 57 and the highest score was a 98 in both classes. Both classes are very similar in test scores. Statistics: Stem-and-Leaf Plots The data from the two classes indicates that the test given appears to be valid. Statistics: Stem-and-Leaf Plots Now compare the data from the two periods. Then the last digit in 88 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 60 will match up with the stem 6.

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 8 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. N 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.
