Tables vs. Graphs

Edward Tufte stated, "Tables usually outperform graphics in reporting on small data sets of 20 numbers or less. The special power of graphics comes in the display of large data sets," (1983).

When is it better to use tables then graphs when displaying data?

Look at the site below to help answer the question better, there are a bunch of graphs and charts, but what displays information better?

Graphs, Charts, Tables, Oh MY!

Over the years graphs, charts and tables have become a huge success in communicating information visually. In most cases it has made it easy for people to read, analyze, and interpret data. But we have to be careful when using these tools to display data because it is not always appropriate. For me using graphs in the classroom setting has been a big benefit when it comes to math. I think graphs are more perceptible to younger students than charts, what do you think? Why?

Are graphs and charts misleading?

When is it appropriate to use a visual display of quantitative information in a classroom?
