Figure 9.6 Cell Plot for SAT Scores

From Figure 9.6, you notice the following:

•

Hawaii has the lowest verbal scores for 2004, and South Dakota has the highest verbal scores for 2004.

•

There is a contrast between Hawaii’s math and verbal scores. Hawaii has average math scores (represented by gray color values) but low verbal scores (represented by blue color values). Hawaii appears to be an outlier, since it has a strikingly different pattern for its math scores and its verbal scores.

•

There is very little contrast between North Dakota’s math and verbal scores. North Dakota’s math and verbal scores are generally high (represented by red color values).

For a description of color themes, see Pop-Up Menu for Cell Plots.
