The probability level of rejecting the null hypothesis is influenced by larger samples, larger observed differences between means, and smaller variance among participants, as these factors increase the statistical power of a test. A smaller observed difference between the means being compared does not increase this probability; it actually makes it harder to reject the null hypothesis because it suggests less effect or difference.
