Assume there is an unknown “true” value.

Assume there is an unknown “true” value. Consider two measurement procedures. One procedure (A) will provide a measure that is less than the true value, and all measurers will present the same measure. The second procedure (B) will provide, on average, a measure equal to the true amount, but it can be either larger or smaller on a random basis. Which measurement procedure do you prefer, assuming your decision will be based on the information obtained?
