Bar Graphs Line Graphs Circle pie graphs Tables
Bar Graphs, Line Graphs & Circle (pie) graphs Tables, charts and graphs are convenient ways to clearly show your data.
Graphs Class A Class B
Graphs have things in common. b b b All graphs have a title. A circle graph has a key. A line and bar graph have a labeled X and Y axis. The X axis is always the independent variable. (What is being changed by the experimenter). The Y axis is always the dependent variable. (what is changed as a result of the independent variable).

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