In the above image, the results from thef-testshow a large p value (.244531, or 24.4531%), so you would not reject the null. However, there’s also another way you can decide: compare your f-value with your f-critical value. If the f-critical value is smaller than the f-value,...
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?
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. Sta...

When you perform a hypothesis test in statistics, a p-value helps you determine the significance of your results. Hypothesis tests are used to test the validity of a claim that is made about a population. This claim that’s on trial, in essence, is called the null hypothesis. ...

Latin-filled formulae. For too long statistics has been classed as tedious and boring, but with this book Andrew Vickers, a biostatisti-cian based in New York, redefines the field of "popular statistics" and shows us that statistics is much more fun and interesting than we might have ...
