Comparing Types of Graphs

September 15, 2010 by eppsteam16 · 2 Comments · Maths, Surveys

Yesterday students explored the advantages and disadvantages of different types of graphs. Students compared a column graph to a pie graph which represented the same information.

Angry graphs

Students noticed that:

Column Graphs

  • can show zero
  • seem easier to read (opinion)
  • easier to compare, same starting point – O

Pie Graph

  • can’t show zero
  • can’t see the number of people surveyed unless you write the fraction next to each section
  • Percentages can make graph clearer

We also discussed how graphs can be manipulated. For example in the survey question: Where do you get angry the most? the only options were yard, oval, home, and sport. We discussed other options that could have been available.

    Hi Team 16. I was reading about the things you had noticed when working with graphs. There is so much information you can get from a good graph! I love pie graphs the best because you can see at glance where the highest and lowest categories are.
