Significant level meaning
WebIf a test of significance gives a p-value lower than or equal to the significance level, the null hypothesis is rejected at that level. Such results are informally referred to as 'statistically significant (at the p = 0.05 level, etc.)'. For example, if someone argues that "there's only one chance in a thousand this could have happened by ... 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.
