9. Wednesday, April 8 Chapter 6.12.2b Histograms

10. Objective: To construct and analyze histograms.

11. Histograms A histogram is a type of bar graph used to display numerical data that has been organized into equal intervals.

12. Histograms Cost of Planes Number of Planes

13. Histograms How many players are between 20 and 23 years old?

14. Histograms How many players are between 20 and 23 years old? 6

15. Histograms How many players are at least 28 years old?

16. Histograms How many players are at least 28 years old? 4 + 8 + 1 = 13

17. Histograms How many players are 33 years old?

18. Histograms How many players are 33 years old? Since the data is in intervals, we can’t determine this.

19. Histograms The histogram shows the wins for basketball league teams. How many teams won 31 games or more?

20. Histograms The histogram shows the wins for basketball league teams. How many teams won 31 games or more? 4 + 10 + 8 = 22

21. Histograms The histogram shows the wins for basketball league teams. How many teams won 40 games or less?

22. Histograms The histogram shows the wins for basketball league teams. How many teams won 40 games or less? 2 + 4 + 4 = 10

23. Histograms Histograms are an excellent way to show continuous data; such as weight, height, and how much time.

24. Histograms When the categories are an item ( such as favorite movies or countries), a bar graph is a better choice.

25. Histograms When the categories are numerical, a histogram is a better choice.

26. Histograms The table represents the number of daily visitors to certain state parks. Draw a histogram to represent the data. How to Draw a Histogram. Step 1 - Transfer the intervals (1 st column) to the horizontal axis of the graph and label.

27. Histograms The table represents the number of daily visitors to certain state parks. Draw a histogram to represent the data. How to Draw a Histogram. Step 1 - Transfer the intervals (1 st column) to the horizontal axis of the graph and label.

28. Histograms The table represents the number of daily visitors to certain state parks. Draw a histogram to represent the data. How to Draw a Histogram. Step 2 - Transfer the range of the frequency data to the vertical axis of the graph and label. The numbers should begin at zero.

29. Histograms The table represents the number of daily visitors to certain state parks. Draw a histogram to represent the data. How to Draw a Histogram. Step 2 - Transfer the range of the frequency data to the vertical axis of the graph and label. The numbers should begin at zero.

30. Histograms The table represents the number of daily visitors to certain state parks. Draw a histogram to represent the data. Note – these intervals must start at zero and be consistent, but do not have be one.

31. Histograms The table represents the number of daily visitors to certain state parks. Draw a histogram to represent the data. How to Draw a Histogram. Step 3 - For each interval draw a bar whose height is given by the frequencies.
