SUMMARY

The discussion focuses on evaluating the performance of five clocks based on their accuracy relative to the WWV signal at noon. Participants emphasize the importance of understanding the rate of gain or loss of each clock rather than their absolute time readings. A clock that consistently loses exactly one minute per hour is deemed more reliable than one that fluctuates within five minutes of the correct time. The concept of standard deviation is introduced as a potential method for assessing the clocks' performance.

PREREQUISITES
  • Understanding of timekeeping principles
  • Familiarity with the WWV time signal
  • Basic knowledge of standard deviation
  • Concept of clock accuracy and precision
NEXT STEPS
  • Research methods for calculating standard deviation in timekeeping
  • Explore the principles of clock accuracy and reliability
  • Learn about the WWV time signal and its applications
  • Investigate different types of clocks and their mechanisms
USEFUL FOR

Anyone involved in timekeeping, including horologists, naval personnel, and engineers focused on precision instruments.

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.
