P-value is the level of marginal significance within a statistical hypothesis test, representing the probability of the occurrence of a given event.

This all might sound complicated, but finding the p value is an invaluable test in statistics and it is essential that your graphing calculator can do the hard work for you.

The method is illustrated using the small sample testing of a binomial proportion and the exact analysis of 2 × 2 tables as examples. The resulting P-value is compared with the previous two methods ...

Explore what a one-tailed test is in statistics, learn how it works, its application in finance, and understand its significance with a real-world example.

This example illustrates how to use PROC MULTTEST to multiplicity-adjust a collection of raw p-values obtained from some other source. This is a valuable option for those cases where PROC MULTTEST ...

The p value from the two-sample t-test has been disparaged for its apparent inability to provide a measure for the magnitude of the mean effect. However, by knowing the p value and the sample size, a ...
