Campaign!

G'day, fellow RationalWikians! Don't forget to visit the Campaign page of the 2016 Board of trustees election in order to make your voice heard. Suggested activities include:

  • Endorsing select candidates (lending a hand to your loyal henchmen and/or glorious overlords!)
  • Anti-endorsing select candidates (character-assassinating your hated opponents!)
  • Providing moar goat (please wipe afterwards)
  • Just asking questions to the candidates

Your participation might help other users better direct their votes. More importantly, it'll show the world that we've yet to go full Citizendium in terms of election hype!

Accuracy and precision are measurements within science and engineering of how well results fit with reality and how reliable they are. Accuracy is a concept that describes the degree to which a measurement approximates the actual value, whereas precision measures how reproducible a result is.

[edit] Low accuracy or precision

An experiment or test with low accuracy or precision is still useful if the other is reasonably high. A test with low precision can be improved with more samples as each data point will still average out as an accurate value (diagram 1). On the other hand, a test with low accuracy can still be useful if it is precise, because we can conclude that there must be a reproducible and systematic error in the measurement causing the lack of accuracy (diagram 2). In science, this is particularly useful for refining theories and experiments.
