    Error Labs Rate
Click For Summary
The discussion revolves around calculating the collection rate error for a lab experiment involving the collection of radioactive material on a wire. The collection rate (CR) is defined as CR = W/(W+R), where W is the material on the wire and R is the residue in the vial. Participants debate the correct approach to error propagation, particularly regarding the treatment of W+R and the use of Poisson statistics for error calculations. Key points include the need to consider the correlation between W and R when calculating errors, as well as the distinction between counts and count rates in measurements. The conversation emphasizes the complexity of error analysis in this experimental setup, particularly with respect to systematic errors and measurement uncertainties.

I accept - not a good example. But there are various tax 'rates' that are dimensionless.

And you pay your income taxes once per year. Or sales tax once per purchase. It makes a difference. Final answer.
