That applies to errors too. There are three steps in error analysis of most experiments. The first, propagation of errors, can be performed even before the experiment is performed. The second, measuring the errors, is done during the experiment. And the third, comparison with accepted values, is performed after the experiment is completed.
There are two fundamentally diferent types of experimental error. Statistical errors are random in nature: repeated measurements will difer from each other and from the true value by amounts which are not individually predictable, although the average behavior over many repetitions can be predicted.
The error in an experimentally measured quantity is never found by comparing it to some number found in a book or web page.
If you cannot measure it, you cannot know it. That applies to errors too. There are three steps in error analysis of most experiments. The first, propagation of errors, can be performed even before the experiment is performed. The second, measuring the errors, is done during the experiment.
