WebMar 10, 2024 · P-value is a measurement that assumes the null hypothesis is correct, meaning that if the value is small, then you can reject the null hypothesis in favor of the alternative hypothesis. A large p-value typically means that the data point or set you measured aligns with the null hypothesis, making it the more likely outcome. WebFeb 13, 2024 · Formally, the p-value is the probability that the test statistic will produce values at least as extreme as the value it produced for your sample.
