and if they disagree then it is not because they have a different view of effect-size, but because the methods might be approximations of the actual p-value and are not exact methods to compute the p-value. Yet

In Statistics, P-value is defined as the measure of the probability that an observed difference might have occurred just by random chance. To learn the definition of P-value, formula, table and examples, visit BYJU’S.
What is the p-value in statistics? The p-value (denoted p) for a set of data is the probability that the given data (or something even more unusual) would occur if the hypothesis being tested is not true. How do you find p-value from z-statistic? To calculate the p-value, first ...
Thepvalueis a number, calculated from a statistical test, that describes how likely you are to have found a particular set of observations if the null hypothesis were true. Pvalues are used inhypothesis testingto help decide whether to reject the null hypothesis. The smaller thepvalue, the ...
A hypothesis test is the formal procedure that statisticians use to test whether a hypothesis can be accepted or not. A hypothesis is an assumption about something. It is a four-step process. Step one: write the hypothesis. Read Hypothesis Testing Definition, Steps & Examples Lesson ...

value is a threshold or boundary in statistical hypothesis testing that helps us decide whether to reject thenull hypothesisor not. It is determined by the desired significance level(α), which represents the probability of making a Type I error (incorrectly rejecting a true null hypothesis). ...
