8. 4. Which instrument is most popular? 5. What instrument played is the next to least popular? 6. 300 students in a school play any one musical instrument. How many students play guitar? Piano Drums 96

9. 7. Make a double-bar graph of the data in the table. Number of Laps 2000 1990 1995 16 12 8 4 0 Average Number of Laps Run Boys Girls

10. 8. The list shows the number of laps students ran one day. Make a histogram of the data. 4, 7, 9, 12, 3, 6, 10, 15, 12, 5, 18, 2, 5, 10, 7, 12, 11, 15 Number of Students Number of Laps Run 10–14 0–4 5–9 8 6 4 2 0 15–19 Number of Laps

11. Use a bar graph to display and compare data. There are several ways to display data. Some types of displays are more appropriate than others, depending on how the data is to be analyzed. x x x x x x Use a line plot to show the frequency of values. 1 7 9 2 5 3 6 1 Use a stem-and-leaf plot to show how often data values occur and how they are distributed.

12. Use a frequency chart to show the frequency and cumulative frequency of an event Use a circle graph to show how a set of data is divided into parts. English Exam Grades GradesFrequency Cumulative Frequency 60–69 70–79 80–89 90–99

13. For the project… You will create a poster or PowerPoint to present your assigned type of graph to your classmates. You will be given the guidelines to help you receive an A and a rubric of exactly how you will be graded. If you need help, feel free to use your textbook, rubric, peers, teachers, or the Internet to help you out!

14. Types of Graphs 1) Frequency Tables 2) Stem and Leaf Plots 3) Line Plots 4) Bar Graphs 5) Histograms 6) Circle Graphs

And I want 5 intervals….so what’s 480 divided by 5? 96! I will make my intervals 100 because that’s just a little bit more. 120-219220-319320-419420-519520-619
