I would like to choose point 6: Statistical significance indicates a scientifically or substantively important relation has been detected from page 341.
Statistical significance doesn’t mean that a finding is important or practically relevant. If the null hypothesis were true, the observed result is not happened by chance. The observed effect is unlikely to be a random.
Even in large studies, when it is not really matter in practice, the very small effects or minor errors in assumptions can show up as very statistically significant. A low p-value for the null hypothesis doesn’t necessarily mean the result is important in real life. It just means that the observed data are unlikely if the null hypothesis were true.
