3 cars, one car has a small straw, the other a medium and the last a large straw. i'm testing for which will go faster for the project.
what would be the control group? thanks.|||The control group would be a car with no straw|||Medium, as this is the one you're comparing the other results to.|||There really is no control. The control would be a car without a straw at all. You would test that car to get your base numbers. Then test other cars with different size straws, and compare the results to the base numbers. The cars with the straws make up the experimental group.
I hope I helped you. To be honest, I'm confused as to what you mean by "straws." LOL
