## 6.4: Stem and Leaf Plots

One simple graph, the stem-and-leaf graph or stemplot , comes from the field of exploratory data analysis. It is a good choice when the data sets are small. To create the plot, divide each observation of data into a stem and a leaf. The leaf consists of a final significant digit.

For example, 23 has stem two and leaf three. The number has stem 43 and leaf two. Likewise, the number 5, has stem and leaf two.

The decimal 9. Write the stems in a vertical line from smallest to largest. Draw a vertical line to the right of the stems. Then write the leaves in increasing order next to their corresponding stem. For Susan Dean's spring pre-calculus class, scores for the first exam were as follows smallest to largest : 33; 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; The stemplot shows that most scores fell in the 60s, 70s, 80s, and 90s.

For the Park City basketball team, scores for the last 30 games were as follows smallest to largest : 32; 32; 33; 34; 38; 40; 42; 42; 43; 44; 46; 47; 47; 48; 48; 48; 49; 50; 50; 51; 52; 52; 52; 53; 54; 56; 57; 57; 60; 61 Construct a stem plot for the data. The stemplot is a quick way to graph data and gives an exact picture of the data. You want to look for an overall pattern and any outliers. An outlier is an observation of data that does not fit the rest of the data.

It is sometimes called an extreme value. When you graph an outlier, it will appear not to fit the pattern of the graph. Some outliers are due to mistakes for example, writing down 50 instead of while others may indicate that something unusual is happening. It takes some background information to explain outliers, so we will cover them in more detail later. The data are the distances in kilometers from a home to local supermarkets.

Create a stemplot using the data: 1. The value Values appear to concentrate at three and four kilometers. The following data show the distances in miles from the homes of off-campus statistics students to the college.

Create a stem plot using the data and identify any outliers:. A side-by-side stem-and-leaf plot allows a comparison of the two data sets in two columns. In a side-by-side stem-and-leaf plot, two sets of leaves share the same stem.

The leaves are to the left and the right of the stems. Table 2. Construct a side-by-side stem-and-leaf plot using this data. The table shows the number of wins and losses the Atlanta Hawks have had in 42 seasons.

Create a side-by-side stem-and-leaf plot of these wins and losses. Another type of graph that is useful for specific data values is a line graph. In the particular line graph shown in Example 2. The frequency points are connected using line segments. In a survey, 40 mothers were asked how many times per week a teenager must be reminded to do his or her chores. The results are shown in Table 2. In a survey, 40 people were asked how many times per year they had their car in the shop for repairs.

Construct a line graph. Bar graphs consist of bars that are separated from each other. The bars can be rectangles or they can be rectangular boxes used in three-dimensional plots , and they can be vertical or horizontal. The bar graph shown in Example 2. By the end of , Facebook had over million users in the United States.

Construct a bar graph using this data. The population in Park City is made up of children, working-age adults, and retirees. Construct a bar graph showing the proportions. The columns in Table 2. Public Schools for the class of , percentages for the Advanced Placement examine population for that class, and percentages for the overall student population. Create a bar graph with the student race or ethnicity qualitative data on the x -axis, and the Advanced Placement examinee population percentages on the y -axis.

Park city is broken down into six voting districts. The table shows the percent of the total registered voter population that lives in each district as well as the percent total of the entire population that lives in each district.

Construct a bar graph that shows the registered voter population by district. As an Amazon Associate we earn from qualifying purchases. Want to cite, share, or modify this book? This book is Creative Commons Attribution License 4.

Histograms. Stem and leaf plots. Two-way tables. Box plots. Scatterplots. Time-series plots. In helping students to develop their data analysis skills, it is important.

Histograms are one of the most widely used methods for displaying the observed values for a variable. However, they do take a little bit of effort to draw. Sometimes it can be quite useful to make use of simpler, if less visually appealing, options. One such alternative is the stem and leaf plot. To a first approximation you can think of a stem and leaf plot as a kind of text-based histogram.
