Why graph data?
Activity:

Work in small groups to graph data on transparencies.

Develop graph assessment rubric - criteria for good graphs.
Self-Assessment:
Type(s) of graphs did you use to represent the data?
Explain your choice of graph type.
Evaluate your graphs: are they excellent, good, adequate or poor?
What criteria did you use to evaluate your graph(s)?
(i.e., How do you know that your graph is good or poor?)
Be explicit; list the criteria and state how you met each one.
