Significant level meaning
WebJul 31, 2024 · To say that a result is statistically significant at the level alpha just means that the p-value is less than alpha. For instance, for a value of alpha = 0.05, if the p-value is greater than 0.05, then we fail to reject the null hypothesis. There are some instances in which we would need a very small p-value to reject a null hypothesis. WebHowever, Levene’s test is statistically significant because its p < 0.05: we reject its null hypothesis of equal population variances. The combination of these last 2 points implies that we can not interpret or report the F-test shown in the table below. As discussed, we can't rely on this p-value for the usual F-test.

WebTraditionally, experimenters have used either the 0.05 level (sometimes called the 5% level) or the 0.01 level (1% level), although the choice of levels is largely subjective. The lower the significance level, the more the data must diverge from the null hypothesis to be significant. Therefore, the 0.01 level is more conservative than the 0.05 ...

Previously, clinicians often had to wait an average of 6 hours with the lower-sensitivity, lower-precision cTn assays to see a conclusive increase in plasma cTn levels after the first troponin measurement, but today's high-sensitivity cTn tests that are separated by a mere 2 to 3 hours can be highly …
WebZ-scores are standard deviations. If, for example, a tool returns a z-score of +2.5, you would say that the result is 2.5 standard deviations.
