Human Population Centers and Monarch Reports
Any Correlation?

Be careful about potential pitfalls when interpreting data!

Mike Quinn, entomologist with Texas Parks and Wildlife, wonders if there is a correlation between the location of sightings in Texas and Texas population centers. "You might offer the students several different maps and ask them which one shows the best correlation to current monarch reports," he suggested.

Take a look. What do you think?
