1. Comparing Graphs There is are some fine details that you must be aware of when interpreting data

2. Compare these two precipitation graphs. What conclusions can you make about the precipitation for these two areas?

5. Now, take a look at the scale for each graph. What do you notice?

7. Adapted from Slides by Mr. Armfield Science Department Deerfield HS, Deerfield IL Comparison Graphing In order for you to accurately compare graphs of this nature, you must keep the scales the same. Otherwise, you might incorrectly analyze your data. Lets take a look at the two graphs again…

8. First set of graphs with different scales for each.

9. First set of graphs with the same scale for each. What do you notice? How does your conclusion change?

10. Second set of graphs with different scales for each.

11. First set of graphs with the same scale for each. What do you notice? How does your conclusion change?
