I'm conducting a project where I determine which factors (3 in total) contribute to the accuracy in which one would hit a dartboard. Each factor has two levels, low and high. For example, one of the factors is distance and the lowest distance (closest to the dart board) is 2 meters while the highest distance is 4 meters. Another factor I'm using is the left and right hand to throw.
My problem is, how do I measure the response? should I indicate on the dart board two areas where one is considered a bulls-eye (success) and the other a failure? Or should I measure the distance in centimeters between the bulls-eye and the dart to determine which dart has come closest?
which is the appropriate method?
