A naval destroyer is testing five clocks. Exactly at noon, as determined by the WWV signal, on the successive days of a week the clocks read as follows.

How would you arrange these five clocks in the order of their relative value as good timekeepers? Justify your choice.

Heard of standard deviation?
Also rememebr that you don't necessarily care what the time says as long as you know how fast/slow it is from the real time and what the rate is.
A clock that loses EXACTLY 1minute/hour might be better than something which is always within 5mins of the correct time.
