P Value Definition A p value is used inhypothesis testingto help yousupport or reject the null hypothesis. The p value is the evidenceagainstanull hypothesis. The smaller the p-value, the stronger the evidence that you should reject the null hypothesis. ...
What is the null hypothesis, alternative hypothesis, and p value? What is p-value in statistics? Is it statistically significant? If the p-value is not statistically significant, what is the clinical significance? What hypothesis test should be run for two categorical variables?
What are t values and p values in statistics?Runkel, Patrick
To wit: Because the p-value is very low (< alpha level), you reject the null hypothesis and conclude that there's a statistically significant difference. In this way, T and P are inextricably linked. Consider them simply different ways to quantify the "extremeness" of your results under th...
If, in a (two-tail) hypothesis test, the p-value is 0.1367, what is your statistical decision if you test the null hypothesis at the 0.08 level of significance? If, in a (two-tail) hypothesis test, the p-value is 0.0126, what is your statistical decision if you test the nu...
In “regular” mathematics, a parameter refers to a value within an equation that is transferred throughout the equation. For example,mandbare parameters in the slope equationy=mx+b. However, the parameter definition in statistics is quite different. Parameters in statistics are used to describe ...
This chapter discusses statistics and its significance. Statistics are quantities that have been calculated from sample data; a single quantity that has been so calculated is called a statistic. The application of statistical techniques is so widespread and the influence of statistics on daily lives ...
The p-value is a probability. For the pattern analysis tools, it is the probability that the observed spatial pattern was created by some random process. When the p-value is very small, it means it is very unlikely (small probability) that the observed spatial pattern is ...

Mathematically, the p-value is calculated using integral calculus from the area under the probability distribution curve for all values of statistics that are at least as far from the reference value as the observed value is, relative to the total area under the probability distribution curve.
