For example, imagine we studied the effect of a new drug and got a p-value of 0.03. This means that in 3% of similar studies, random chance alone would still be able to produce the value of the test statistic that we obtained, or a value even more extreme, even if the drug had no effect at all!

Old Italic and Old Latin P, which derives from Greek Pi, and is the ancestor of modern Latin P. The Roman P had this form (𐌐) on coins and inscriptions until the reign of Claudius, c. 50AD (see also Claudian letters).

To compare three different diets, use an ANOVA instead – doing multiple pairwise comparisons will result in artificially low p values and lets you overestimate the significance of the difference between groups.

To see where those degrees of freedom come from, consider the independent random variables X and Y, which both follow the χ²-distributions with d 1 and d 2 degrees of freedom, respectively. In that case, the ratio (X/d 1)/(Y/d 2) follows the F-distribution, with (d 1, d 2)-degrees of freedom. For this reason, the two parameters d 1 and d 2 are also called the numerator and denominator degrees of freedom.All statistical tests have a null hypothesis. For most tests, the null hypothesis is that there is no relationship between your variables of interest or that there is no difference among groups. The calculation of the p value depends on the statistical test you are using to test your hypothesis: The p-value from F-score is given by the following formulae, where we let cdf F,d1,d2 denote the cumulative distribution function of the F-distribution, with (d 1, d 2)-degrees of freedom: Ruppel, Klaas; Aalto, Tero; Everson, Michael (2009-01-27).

Most English words beginning with ⟨p⟩ are of foreign origin, primarily French, Latin and Greek; these languages preserve Proto-Indo-European initial *p. Native English cognates of such words often start with ⟨f⟩, since English is a Germanic language and thus has undergone Grimm's law; a native English word with initial /p/ would reflect Proto-Indo-European initial *b, which is so rare that its existence as a phoneme is disputed. Everson, Michael; Baker, Peter; Emiliano, António; Grammel, Florian; Haugen, Odd Einar; Luft, Diana; Pedro, Susana; Schumacher, Gerd; Stötzner, Andreas (2006-01-30).

The Latin letter P represents the same sound as the Greek letter Pi, but it looks like the Greek letter Rho. It is the alternative hypothesis that determines what "extreme" actually means, so the p-value depends on the alternative hypothesis that you state: left-tailed, right-tailed, or two-tailed. In the formulas below, S stands for a test statistic, x for the value it produced for a given sample, and Pr(event | H 0) is the probability of an event, calculated under the assumption that H 0 is true:The p value is a proportion: if your p value is 0.05, that means that 5% of the time you would see a test statistic at least as extreme as the one you found if the null hypothesis was true. Example: Test statistic and p valueIf the mice live equally long on either diet, then the test statistic from your t test will closely match the test statistic from the null hypothesis (that there is no difference between groups), and the resulting p value will be close to 1. It likely won’t reach exactly 1, because in real life the groups will probably not be perfectly equal.
