A confounding variable is an outside variable beyond the control of the race teams and official. What are some confounding variables that could contribute to the speed of the tracks?

rain and turns

Explanation:

There are various confounding variables that could contribute to the speed of the track, one of which is rain. Rain is something that the race teams and officials cannot control and affects the speed at which racecars can operate on a track. This is because the Rain wets the tracks which prevents the cars wheels from properly gripping the track and instead causes them to skid. Another confounding variable would be turns.
