Types of Graphs and Graphing Rules Unit 1
Types of Graphs There are three types of graphs that we will use in this class: Line Graphs Bar Graphs Pie Graphs
Line Graphs These graphs are used to show continuous change, usually over time For example, you might want to show the progress of something over a period of time
Bar Graphs These graphs are used to show a comparison between data or between different IVs For example, when comparing the number of students who like various types of fruit
Pie Graphs These are used to show the different parts or percentages of a whole For example, the percentages of students at Wagner who are involved in the various clubs and those who are not
Graphing Rules All graphs must have a Title Usually in the form of “The Effect of the IV on the DV” All axes should be labeled with titles and the units of measurement All integers along each axis should be spaced equally and full use made of the entire graphing space
Graphing Rules The independent variable is graphed along the horizontal X-axis The dependent variable is graphed along the vertical Y-axis Always provide a key or legend when graphing more than one set of data
On the Axes below Attach the labels to the appropriate place on the graph
