In null-hypothesis significance testing, the p-value is the probability of obtaining test results at least as extreme as the result actually observed, under the assumption that the null hypothesis is correct. A very small p-value means that such an extreme observed outcome would be very unlikely under the null hypothesis. Reporting p-values of statistical tests is common practice in academic publications of many quantitative fields. Since the precise meaning of p-value is hard to grasp, mi… Web13 nov. 2024 · In statistics, the p-value is the probability of obtaining the observed results of a test, assuming that the null hypothesis is correct. Well, it is just one of the definitions of the p-value. It is comparatively easy to understand the p-value after you understand what null hypothesis is.
