... Error and Data Analysis Nor does error mean "blunder". Reading a scale backwards, misunderstanding what we are doing or walloping into a partner's measuring apparatus are blunders which can be caught and should simply be disregarded. Obviously, it cannot be determined exactly how far off a measurem ...

Statistical Hypothesis Testing for Assessing Monte Carlo Estimators
... pothesis H given the data x, Fisher urged the adoption of direct probability P r(x|H) in an attempt to argue “from observations to hypotheses” [7].

Statistical Hypotheses
... In the example above, we calculated the P-value of the test by finding the area to the left of the standardized test statistic z on the standard normal curve. Notice that the example above was also a left-tailed test, and that any hypothesis test which is left-tailed will have the P-value calculated ...
