Uncertainty FAQs:


Q: Is uncertainty a situation which involves imperfect and/or unknown information?

A: Yes.

Q: Is uncertainty an unintelligible expression without a straightforward description""?

A: Yes, It arises in subtly different ways in a number of fields, including insurance, philosophy, physics, statistics, economics, finance, psychology, sociology, engineering, metrology, and information science.

Q: Is uncertainty propagated through calculations so that the calculated value has some degree of uncertainty depending upon the uncertainties of the measured values and the equation used in the calculation?

A: Yes.

Q: Is uncertainty often implicit?

A: Yes, while for any serious use an explicit statement of the measurement uncertainty is necessary.

Q: Is uncertainty often an important factor in economics?

A: Yes.

Q: Is uncertainty given as the square root of the resulting variance?

A: Yes.

Q: Is uncertainty about the human definitions and concepts?

A: Yes, and not an objective fact of nature.

Q: Is uncertainty larger than the standard deviation of the repeated measures?

A: Yes, and it appears evident that the uncertainty does not depend only on instrumental precision.

Q: Is uncertainty by describing new research that contradicts past research without providing context for the change Other times?

A: Yes, and journalists give scientists with minority views equal weight as scientists with majority views, without adequately describing or explaining the state of scientific consensus on the issue.

Q: Is uncertainty described in the "Guide to the Expression of Uncertainty in Measurement" published by ISO?

A: Yes.

Q: Is uncertainty a central concept quantifying the dispersion one may reasonably attribute to a measurement result?

A: Yes.

Q: Is uncertainty an irreducible property of nature or if there are "hidden variables" that would describe the state of a particle even more exactly than Heisenberg's uncertainty principle allows?

A: Yes.

Q: Is uncertainty involved in every measurement?

A: Yes, such as measuring a distance, a temperature, etc.

Q: Is uncertainty designed into games?

A: Yes, and most notably in gambling, where chance is central to play.

Q: Is uncertainty ± one tenth?

A: Yes, and it is required to be explicit: 7001105000000000000♠10.

Q: Is uncertainty often interpreted by the public as ignorance?

A: Yes.
