![]() For instance, to denote the number 25, the stem could be 2 and the leaf 5 (25). Use a stem-and-leaf plot to display the data shown in the table at the left, which represent the monthly average prices (in dollars per pound) charged by 30 retail outlets for fresh tomatoes. The figure to the left of the divider is the stem, and the digits to the right are referred to as leaves. Find step-by-step Statistics solutions and your answer to the following textbook question: Organize the data using the indicated type of graph. Yes, because there is a frequency of a score of 165. a variant of the frequency distribution, uses a subset of the original digits as class descriptors. No, because there are no bars, or frequencies, greater than an IQ of 160. Yes, because there is a bar in the 150-159 class. ![]() If you want to add a data point to the plot, youd look for the right place on the stem and add it on the right. In the turtles example the categories are number of turtles from 0 to 9, 10 to 19, 20 to 21 and so on. No, because there is a bar in the 150-159 class. Stem and leaf plots show for each category in the stem how many and which data points were measured that fall into this category. 60-70 (f) What percent of students had an IQ of at least 130? (g) Did any students have an IQ of 161? A. Point out any unusual features of the data that you can see from the stem and leaf. Make a stem-and-leaf display of the sizes of the vineyards in acres. 100-109 (e) Which class has the lowest frequency? A. Find step-by-step solutions and your answer to the following textbook question: The data set provided contains the data from the earlier exercises. Record a leaf for every observation beside its stem value 6. Draw a vertical line to the right of the stem values 5. ![]() List the possible stem values (in decreasing order) in a vertical column 4. 5 to 20 stems is recommended (w/ more data more stems is okay) 2. Frequency polygons are very similar to histograms, except histograms have. All of the above., Questions 2 to 6 refer to the following information. Make sure the stem value is only one digit. Arrange the leaf values from smallest to largest. 65, 1 75, 4 85, 13 95, 41 105, 60 115, 40 125, 29 135, 8 145, 2 155, 2 B. Histogram, Frequency polygons do not list the raw data, as stem and leaf plots do. Study with Quizlet and memorize flashcards containing terms like For a stem-and-leaf display A. The class width is _ (c) Identify the classes and their frequencies. For this purpose, a random sample of 55 plots, each of size 100 square meters, is used. (a) How many students were sampled? (b) Determine the class width. Suppose an archaeologist wants to estimate the density of ferromagnetic artifacts in the Tara region. The frequency of each class is labeled above each rectangle. IQs are measured to the nearest whole number. The following frequency histogram represents the IQ scores of a random sample of seventh-grade students.
