WebThe formal definition of a p-value is that it is the probability of observing data that is as extreme or more extreme than the data you have observed, assuming the null hypothesis is true. There’s two things to keep in mind about this definition: The p-value is about the probability of our data. It is not about the probability of our hypothesis. WebP values (or probability values) are used in hypothesis testing to represent the chance that, assuming the null hypothesis is true, you could observe the result in your study or one even more extreme. P values help researchers avoid publication errors, specifically Type I Errors.

WebIn the majority of analyses, an alpha of 0.05 is used as the cutoff for significance. If the p-value is less than 0.05, we reject the null hypothesis that there's no difference between the means and conclude that a significant difference does exist. If the p-value is larger than 0.05, we cannot conclude that a significant difference exists.
