The two tires on a bicycle experience wear much like car tires do; repeated contact with the road or sidewalk will wear down the raised rubber, giving the tire less traction. A major tire manufacturer has developed a new bicycle tire design they hope will reduce wear. After running several rounds of testing in laboratory conditions, they want to test the tires in real-life biking conditions. They find 20 volunteers who bike on a daily basis. The volunteers are each given a new bike of the same model for the duration of the experiment. The volunteers are to bike as they normally would for a month, then return the bike to have the wear of the tires measured, determined by millimeters of tire depth remaining. The manufacturer wants to compare the new tire to the standard model tire, so they will use the standard model in the experiment as a control group. Describe the primary advantage of using a matched pair design in the context of this experiment.
