1. Graphs and Data By: Shelly Jamison

2. Bar Graph Use a bar graph to compare data Use a bar graph to compare data

3. Double Bar Graph Use a double-bar graph to compare data by category. Double: (groups like boy/girl, or grade levels)

4. Line Graph Use a line graph to show how data changes over time.

5. Double Line Graph Use a double- line graph to show how data changes over time. Double: (groups, sections, categories)

6. Line Plot Use a line plot to keep count of data as it is collected or to show frequencies of repeated amounts.

7. Circle Graph Use a circle graph to compare parts of a group to the whole group.

8. Eye color of Mrs. Jamison’s Students

9. Numerical Data Numerical data- Values that can be measured

10. Categorical Data Categorical Data- Values that can be sorted into groups or categories Categorical Data- Values that can be sorted into groups or categories

11. Scale- $0-$200 -Where does my graph start/Where does it end? Interval of the scale- $50 -Distance between two numbers

12. Let’s Practice!!

13. What type of graph would the following information be displayed on? A student is trying to get his family to start recycling at home. He wants to show his family research of how many tons of garbage his town produced over a few years. A student is trying to get his family to start recycling at home. He wants to show his family research of how many tons of garbage his town produced over a few years.

14. Line Graph Is this data categorical or numerical? What is the scale of this graph? (Amount of garbage) What is the interval?

15. What type of graph would the following information be displayed on? Jonathan wants to separate his daily activities. He wants to see what he does each day that takes up the most time. What kind of graph he should use? Jonathan wants to separate his daily activities. He wants to see what he does each day that takes up the most time. What kind of graph he should use?

16. Circle Graph

17. What type of graph would the following information be displayed on? Mrs.Conquest’s class went to the zoo. She surveyed her class to see which exhibit the students liked most and then tried to figure out what kind of graph she should use. What kind of graph do you think she should use? Mrs.Conquest’s class went to the zoo. She surveyed her class to see which exhibit the students liked most and then tried to figure out what kind of graph she should use. What kind of graph do you think she should use?

18. Bar Graph What is the scale of this graph? Looking at the scale, what is the interval? Is this information categorical or numerical?
