What is a Stem and Leaf Plot

What is a Stem and Leaf Plot In a stem leaf plot of quantitative data, each value is divided into two portions- a stem and a leaf. Stem represented on a vertical axis whereas leaves of the corresponding stem will be represented on the horizontal axis. For an example 35, 39, 30 can be represented as 3 | 0 5 9 Where 3 is the stem and 0, 5 and 9 are the leaves. Example: - The following are the scores of 18 college students on a statistic test: 52 80 96 87 95 81 61 86 50 64 71 87 57 Construct a stem leaf plot. Solution: - To construct a stem leaf plot for these scores, we split each score into two parts. The first part contains the first digit, which is called stem. The second part contains the second digit, which is the leaf. Thus, for the score of the first student, which is 75, 7 is the stem and 5 is the leaf. We observe from the data the stem for all the scores 5, 6, 7, 8 and 9 because all scores lie in the range of 50 to 98. Now we will create the leaf for each of this stem. 5 | 0 2 7 6 | 1 4 7 | 1 8 | 0 1 6 7 9 | 5 6 Example: - Construct a stem leaf plot for the following data. 57 35 18 21 51 47 21 46 42 39 Solution: - 1 | 8 2 | 1 1 3 | 5 9 4 | 2 6 7 5 | 1 7
