What makes a statistic less likely to occur under the null hypothesis?
The smaller the p -value, the less likely your test statistic is to have occurred under the null hypothesis of the statistical test. Because the test statistic is generated from your observed data, this ultimately means that the smaller the p -value, the less likely it is that your data could have occurred if the null hypothesis was true.
