Can you please provide the source for the question? Was it the PM Prepcast's exam simulator or a product from another vendor?
To be honest this one has me confused as well, as you would typically see median and mean used to describe central tendency among a collection of data points, not as a quality of cost estimates. But I might be misunderstanding the context. Did the simulator provide additional feedback other than the correct answer?
