A stem-and-leaf plot resembles a histogram on its side. Create a side-by-side stem-and-leaf plot of these wins and losses. Notice the similarity between histograms and stem-and-leaf plots. The table shows the number of wins and losses the Atlanta Hawks have had in 42 seasons. Presidential Ages at Inauguration: President Construct a side-by-side stem-and-leaf plot using this data. The two following tables show the ages of presidents at their inauguration and at their death. The leaves are to the left and the right of the stems. In a side-by-side stem-and-leaf plot, two sets of leaves share the same stem. Eight out of the 31 scores or approximately 26% were in the 90s or 100, a fairly high number of As.Ī side-by-side stem-and-leaf plot allows a comparison of the two data sets in two columns. The stemplot shows that most scores fell in the 60s, 70s, 80s, and 90s. Then write the leaves in increasing order next to their corresponding stem.įor Susan Dean’s spring pre-calculus class, scores for the first exam were as follows (smallest to largest):ģ3 42 49 49 53 55 55 61 63 67 68 68 69 69 72 73 74 78 80 83 88 88 88 90 92 94 94 94 94 96 100Stem-and-Leaf Graph Stem Stem & Leaf Plots are a way of organising data via their place value to show the distribution of data. Draw a vertical line to the right of the stems. Also known as a Stemplot, Stem & Leaf Display. Step 6: Draw the leaf digits based on the groupings from Step 3. The scores range from 50 to 99 so the tens are 5,6,7,8, and 9. For this sample problem, the stem represents tens. Write the stems in a vertical line from smallest to largest. All that’s really needed to make a simple stemplot is a vertical line: Step 5: Draw the stem numbers. The decimal 9.3 has stem nine and leaf three. Likewise, the number 5,432 has stem 543 and leaf two. For example, 23 has stem two and leaf three. The leaf consists of a final significant digit. The result is a graph that displays the sorted data in groups, or classes. This type of graph uses a stem as the leading part of a data value and a leaf as the remaining part of the value. Thus, the first row of the plot represents sample values of approximately 80, 82, and 83. A stem-and-leaf plot is a method of organizing the data that includes sorting the data and graphing it at the same time. The first row has a stem value of 8 and contains the leaf values 0, 2, and 3. This stem-and-leaf plot shows customer wait times for an online customer service chat with a representative. To create the plot, divide each observation of data into a stem and a leaf. The spread shows how much your data vary. It is a good choice when the data sets are small. Create a side-by-side stem-and-leaf plot of these wins and losses.One simple graph, the stem-and-leaf graph or stemplot, comes from the field of exploratory data analysis.
