P-Value: What It Is, How to Calculate It, and Why It Matters

WebMar 7, 2016 · P-Values A test statistic enables us to determine a p-value, which is the probability (ranging from 0 to 1) of observing sample data as extreme (different) or more extreme if the null hypothesis were true. The smaller the p-value, the more incompatible the data are with the null hypothesis. WebOct 27, 2024 · Briefly put, if you look at the bottom right, you’ll see p-value < 2.2e-16.
