Automobile tires can have a symmetric tread or an asymmetric tread. An experiment is to be conducted to determine whether the stopping distance is the same for both types of tire treads. In previous studies, it was determined that automobile size (small, medium, large) is associated with stopping distance, but automobile type (van, truck, SUV, and so on) is not associated with stopping distance. How could the experiment BEST be conducted

Hello your question lacks the required options here are the options

By blocking on stopping distance

By blocking on tire tread type

By blocking on automobile type

By blocking on automobile size

Without blocking

Answer : By blocking on automobile size

Step-by-step explanation:

The experiment can best be conducted by blocking on the automobile and this is because the Automobile size and the stopping distance are proportionally related (associated ) as seen from the previous experiments hence the best experiment is By blocking on the size of the automobile is very crucial .

we can have a symmetric tread tire or an asymmetric tires fixed on the different types of Automobiles simultaneously and see if the stopping  distance will be affected when we change the tires that way we are blocking on the Automobile size the same type of tires will be fixed at the same time on each automobile size

it's both, now can you answer my most recent question?
