The statement that is being tested against the null hypothesis is the alternative hypothesis. [2] Symbols may include H 1 and H a. A statistical significance test starts with a random sample from a population.
A credible claim of significance is a statement in the article that attributes noteworthiness, or information written about the subject in reliable sources.. Wikipedia's speedy deletion criteria A7, A9 and A11 state that certain pages can be speedily deleted if they don't make a "credible claim of significance or importance" (among other requirements specific to each criterion).
"The statement being tested in a test of statistical significance is called the null hypothesis. The test of significance is designed to assess the strength of the evidence against the null hypothesis. Usually, the null hypothesis is a statement of 'no effect' or 'no difference'." [2] Null hypothesis is often denoted as H 0.
The solution to this question would be to report the p-value or significance level α of the statistic. For example, if the p-value of a test statistic result is estimated at 0.0596, then there is a probability of 5.96% that we falsely reject H 0.
An example of Neyman–Pearson hypothesis testing (or null hypothesis statistical significance testing) can be made by a change to the radioactive suitcase example. If the "suitcase" is actually a shielded container for the transportation of radioactive material, then a test might be used to select among three hypotheses: no radioactive source ...
The term significance does not imply importance here, and the term statistical significance is not the same as research significance, theoretical significance, or practical significance. [1] [2] [18] [19] For example, the term clinical significance refers to the practical importance of a treatment effect. [20]
The following is a list of common claims of significance or importance that, if credible, may be sufficient to pass this threshold.Note that "significance or importance" is intentionally a lower criterion than "notability", and that "credible" does not mean "proven".
For example, "children should eat vegetables", and "those who would sacrifice liberty for security deserve neither" are philosophically normative claims. On the other hand, "vegetables contain a relatively high proportion of vitamins", and "a common consequence of sacrificing liberty for security is a loss of both" are positive claims.
