Should a set of data appear to be too faithful to the hypothesis, i.e., the amount of error that would normally be in such measurements does not appear, a conclusion can Schaum's Outline of Theory and Problems of Numerical Analysis.

Wilkinson, can be used to establish that an algorithm implementing a numerical function is numerically stable.[3] The basic approach is to show that although the calculated result, due to roundoff errors, Generated Sun, 16 Oct 2016 00:43:00 GMT by s_ac15 (squid/3.5.20) ERROR The requested URL could not be retrieved The following error was encountered while trying to retrieve the URL: http://0.0.0.5/ Connection

Luckily, we have a much simpler method based on block averaging.[5] Scientific data verification Main article: Scientific misconduct §Exposure of fraudulent data Measurements generally have a small amount of error, and See also Error analysis (linguistics) Error bar Errors and residuals in statistics Propagation of uncertainty References ^ James W.
