The p value is the probability of obtaining a test statistic as extreme as, or more extreme than, the observed data under the assumption that the null hypothesis is true. It is a conditional probability because it is computed assuming the null hypothesis is true. The p value is not the same as an alpha level, and its value is not necessarily greater than .05 to reject the null hypothesis.
