Quizplus · Accepted Answer

A bathroom scale can have high reliability (consistency) in providing the same weight measurement every time, but low validity (accuracy) if it consistently underestimates or overestimates the actual weight. In this case, the fact that the professional scale at the doctor's office consistently shows a higher weight indicates that the bathroom scale has low validity.
