Question

Quizplus · Accepted Answer

Audrey's scale is consistent in the sense that it consistently measures her weight as 3kg lighter than the Weight Watchers scale. However, it is not valid because it does not provide an accurate measure of her weight. A reliable measure is consistent and produces similar results each time it is used, which Audrey's scale does. Therefore, the best answer is B, as Audrey's scale is reliable in its consistency, but not valid in its accuracy. The option D, placebo, is not applicable in this scenario.
