Unit 1: Experimental Design
DIRECTIONS: Set up the following experiment.
“Carlos is interested in seeing if chewing a lot of a special gum with an ingredient called xylitol (its in Trident and
other brands) helps reduce the number of cavities. Xylitol cannot be eaten by the bacteria that live in the mouth and
cause cavities. He gets 1000 people and splits them up evenly into 5 groups. He does this randomly. He has one
group of people never chew Trident or any gum with xylitol, He has the other 4 groups chew 1 stick, 2 sticks, or 3
sticks a day. Here are his results. ”
