Which practices are sound experimental technique?
Hints
- Three improve a measurement; one only appears to.
- Digits beyond the uncertainty carry no information.
Show the answer
- A. Extracting a constant from the slope of a linearised plot
- B. Reducing the largest uncertainty contribution first
- D. Quoting a result with an uncertainty
Why
Uncertainties, linearised fits and attacking the dominant error term are all sound. Extra digits beyond what the uncertainty supports claim a precision the measurement does not have.
