STEP 11 A GRAPH is an excellent way to present your results, but what kind of graph is best for you? This page should give you some guidance. |

Data & Graphs
A graph is a way to represent data visually. A good graph can make a great deal of complicated measurements easy to understand. Different graphs are better for representing different kinds of data.
PIE GRAPH: A pie graph is best for showing how a group is divided up. If you want to show what percentage (or what portion, or what fraction) of a group falls into each of a number of categories, you would use a pie graph.

BAR GRAPH: A bar graph is best for showing how one variable is affected by another characteristic. Generally, with a bar graph, only one variable is a measurable traits and so it is the only one to have a number associated with them. This variable is plotted on the Y-axis. The other characteristic is usually not measurable.

PICTOGRAPH: A pictograph is virtually the same as a bar graph. Pictures are used in place of plain bars, however. Usually the picture is a symbolic representation of some aspect of the data.
LINE GRAPH: A line graph is best for showing how one variable affects another variable. Generally, with a line graph, both variables are measurable traits and so both have a number associated with them.
