the experiment i chose was about whose hands hand more types of germs boys or girls. They took bacteria samples and DNA tested them to see how many types there were. They found that girls had more bacteria then boys. The dv was boys and girls and the iv was number of germs. This experiment was a good experiment but it didn't say how many subjects it tested. A good follow up experiment would be why girls have more germs .
