WebbGraphically, the p value is the area in the tail of a probability distribution. It’s calculated when you run hypothesis test and is the area to the right of the test statistic (if you’re running a two-tailed test, it’s the area to the left and to the right).

WebbP-Value, or the Probability Value, is the determining factor on a null hypothesis for the probability of an assumed result to be true and being accepted or rejected and acceptance of the alternate result in case of rejection of the assumed result. Statisticians refer to this value for more relevant results. WebbA. The P-value of a test is the probability of obtaining a result as extreme (or more extreme) as the one obtained assuming the null hypothesis is false. B. If the P-value for a test is 0.015, the probability that the null hypothesis is true is 0.015. C. The larger the P-value, the more evidence there is against the null hypothesis. D.
