How To Know Which P Value To Use

1. The p-Value Approach to Hypothesis Testing
The other thing that changes when we apply the correction is the p-value that we would use to decide if there's enough evidence to reject the null hypothesis. What is the behaviour of the p-values? While not necessarily immediately obvious, under the null hypothesis, the p-values for any statistical test should form a uniform distribution between 0 and 1; that is, any value in the interval 0... The use of pvalues is ubiquitous in high-energy physics, appearing in such problems as validating a detector simulation, determining the degree of a polynomial used to model a background shape, identifying outlying data points, and quantifying the significance

What Can You Say When Your P-Value is Greater Than 0.05?

Decision Rule Based on P-value To use a P-value to make a conclusion in a hypothesis test, compare the P-value with α 1. If P ≤ α, then reject H0. 2. If P > α, then fail to reject H0. Recall: A P-value (or probability value) is the probability of getting a value of the the sample test statistic that is at least as extreme as the one found from the sample data, assuming that the null...
A p-value is a number between 0 and 1, but it’s easier to think about them as percentages (i.e. a p-value of 0.05 is 5%). Small p-values (generally under 5%) usually lead you to reject the null hypothesis .

  • • If the Use robust method is selected, then a q-value estimate is used that is more robust for small p-values and a direct finite sample estimate of pFDR (Storey 2002).
  • You would generally use a t-test when you only have 2 groups, and an F-test (ANOVA) when you have 3 or more groups, HOWEVER, some computer programs (SPSS) will give you useful output when you run an F-test on just 2 groups (effect size). The t-value is just the square root of the F-value when there is only 1 degree of freedom.

  • On the final note, it is important to know why it is statistically superior to use P value and confidence intervals rather than P value and hypothesis testing: Confidence intervals emphasize the importance of estimation over hypothesis testing.
