How to calculate a confidence interval from a single value?
Posted:

How does one calculate a confidence interval of a single measurement? Without a standard deviation (not reliable from a single measurement), it does not seem possible to calculate a confidence interval.
Now I know what the standard deviation of this measurement is from a history of this measurement (same method, instruments, operators, etc.). Can I use the historical standard deviation as the standard deviation of the current singlicate measurement to estimate the confidence interval of the current measurement?
