Graphing Which graph should I use?
What is a graph? A graph is a visual way to organize data collected during an experiment.
Types of Graphs • Line graph • Bar graph • Pie graph
Does the graph show continuous data, such as changes over time? • Use a line graph • A line graph is used to compare two things and show how they are related • Often show changes over time
Is the graph comparing two categories of data? • Use a bar graph • Lets us compare groups of data
Does the graph use percentages to describe data? • Pie charts are used to show percentages. • The slices of “pie” represent percentages that must add up to 100.
