1. A student wants to buy a new skateboard. He wants to find out if the size of the wheels affects how far he can coast on the skateboard. He also wants to find out if the type of material the board is made of
affects how far he can coast on the skateboard. He decides to compare two skateboard models that are
the same size but are made of different materials and have different size wheels:
Model 1
Model 2
Plastic skateboard
Large wheels
Wooden skateboard
Small wheels
He pushes off as hard as he can and stands on the skateboard until the skateboard comes to a stop. He
tries each skateboard 5 times to see how far he can go. He uses the same pavement and the same
starting point for all the trials. He finds out that he can coast farther with Model 1. What can he conclude
from this test?
