2. Bar Graph

3. 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

4. Histogram Frequency Test Scores Class Test Scores

5. Histogram b Histograms are used to show the frequency of data. b Very similar to bar graphs, but use intervals on the X axis. b Bars do touch. b Histograms have a title. b Histograms have two axes which are labeled.

6. Line Graph

7. 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 into lines

8. PIE CHART

9. b Each part is called a sector and is labeled. b All angles correct (+2/-2 degrees) b Pie Charts are used to display parts of the data in relation to the entire amount of data. b All Pie Charts need a title. PIE CHART
