conclusion based on data not statistically significant The alpha level (also called significance level) is defined as a hypothesis test attribute that represents the maximal value that is deemed acceptable for the probability of incorrectly rejecting the null hypothesis. Statistical significance is purely a statistical concept and does not represent clinical significance or importance of the statistical finding. A finding of not statistically significant does not mean absence of effect. a conclusion based on the outcome of statistical test means the result of a hypothesis test does not support rejection of the null hypothesis at the specified alpha level.
