1. Bar Graph
Return to Graph

• The purpose of a bar graph is to display and
  compare data.
• Bar graphs use bars to show the data.
• A bar graph must include
• - a title
• - labeled X and Y axes

• - equal intervals are used on the Y axis
• - the bars are evenly spaced apart from each
  other

3. Line Graph
Return to Graph

• A line graph is used to illustrate change over
  time.
• Line graphs need
• - Title
• - Labeled X and Y axes
• - Equal Intervals

• - Data displayed by points connected by
  lines

4. Double Line Graph
Return to Graph

• - Equal Intervals
• - Data displayed by points connected into lines
• - Graph does need a Key

• A double line graph is used to compare two sets
  of related data over time.
• Double line graphs need
• - Title
• - Labeled X and Y axes

11
5. Circle Graph
Return to Graph

• Circle graphs are used to display parts of the
  data in relation to the entire amount of data.
• All circle graphs need a title.

• Each part is called a sector and is labeled.
• All angles correct
• Include a key

2. Double Bar Graph
Return to Graph

• The purpose of a double bar graph is to compare
  two or more sets of data.
• Uses bars to show the data.
• Double bar graphs must include
• - Title
• - 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
