8. 1. Bar Graph b The purpose of a bar graph is to display and compare data. b Bar graphs use bars to show the data. b A bar graph must include: - a title - a title - labeled X and Y axes - labeled X and Y axes - equal intervals are used on the Y axis - the bars are evenly spaced apart from each other Return to Graph

9. 3. Line Graph b A line graph is used to illustrate change over time. b Line graphs need: - Title - Title - Labeled X and Y axes - Labeled X and Y axes - Equal Intervals - Equal Intervals - Data displayed by points connected by lines Return to Graph

10. 4. Double Line Graph b A double line graph is used to compare two sets of related data over time. b Double line graphs need: - Title - Title - Labeled X and Y axes - Labeled X and Y axes - Equal Intervals - Data displayed by points connected into lines - Graph does need a Key Return to Graph

11. 5. Circle Graph b Circle graphs are used to display parts of the data in relation to the entire amount of data. b All circle graphs need a title. b Each part is called a sector and is labeled. b All angles correct b Include a key Return to Graph

12. 2. Double Bar Graph b The purpose of a double bar graph is to compare two or more sets of data. b Uses bars to show the data. b Double bar graphs must include: - Title - Title - Labeled X and Y axes - Labeled X and Y axes - Equal intervals are used on the Y axis - Pairs of bars are equally spaced, but the compared bars are not - Must have a Key Return to Graph
