Questio:we take repeated measurements in experiment, and we can get average x. unfornately, it's not true value of the measuerement. how can we difine the true value?
If we eliminate all systematic errors, take infinite number of measurements and then take the average(by math, it's the average of population, not sample but also not pratical). Is that average the true value? anybody can clearfy it.
