Presenting Data Table vs. Graph Why do you think information is often presented in graphs instead of just in a list or table? What are some kinds of graphs? Bar graph Line graph Pie chart Visual representations to display a relationship not apparent in data tables

Bar Graph When would you use a bar graph? -Categories -Changes over time -When trying to measure change over time, bar graphs are best when the changes are larger. Source:

Line Graph

When smaller changes exist, line graphs are better to use than bar graphs. Line graphs can also be used to compare changes over the same period of time for more than one group.

Line Graphs Which should you use more in science?

Where do we see line graphs?

Pie Chart Pie charts are best to use when you are trying to compare parts of a whole. They do not show changes over time.

Reading Graphs- Practice! Identify the graph that matches each of the following stories: a. I had just left home when I realized I had forgotten my books so I went back to pick them up. b.
