Gary Klass has developed a great website related the topic of misleading and down-right dishonest graphs.  Skim through last semester’s Section 13.3 lecture notes, then take a hard look at Klass’s “How to Construct Bad Charts and Graphs,” paying particular attention to what it takes to make bad charts and graphs.  Professor Klass is currently constructing an updated site, which includes up-to-date, awful graphs.  Several of these graphs include recommended revised versions.   

Now it’s your turn (, of course!).  Find one chart or graph that appears to be misleading or severely slanted.  If you find the chart off line, please scan it then insert as a picture.  If you find the chart online, provide a link to the site where the chart is located.  Why is the graph misleading?  If you were to revise the chart to make it appear more honest, what would you do? 

Theoretically…  If everyone gives two, and you all end up with twenty, how many of you are there in the class? 

Here’s what you’re giving to your classmates:

• Make up a question that you could use in a kindergarten or first-grade classroom to graph data.  (Remember, according the Burris textbook, bar graphs, tally graphs and pictographs are appropriate for this level). 
• Make up a question that you could use in a second- or third-grade classroom to graph data.  (Again, line plots and line graphs are appropriate at this level, as are some types of circle graphs.  Consult your reading for guidelines and examples.)

Your questions should be original and interesting to the level for which they are intended.  Feel free to offer constructive feedback to your classmates regarding the questions they compose.
