In statistical significance testing, the ``p``-value is the probability of obtaining a test statistic result at least as extreme or as close to the one that was actually observed, assuming that the null hypothesis is true. A researcher will often `reject the null hypothesis` when the p-value turns out to be less than a predetermined signific...

p is the symbol for the probability that is associated with the outcome of a test of the null hypothesis (i.e. it is the probability that an observed inferential statistic occurred through chance variation). If the p value is less than or equal to the stated significance level - often set at 5% (p < 0.05) or 1% (p < 0.01) - then the researcher con...

A term in statistics. It helps show whether a difference found between groups that are being compared is due to chance. A small p-value usually means that the difference between groups is not due to chance alone, but is due to some other factor, such as a treatment one of the groups received. A large p-value usually means that the difference betwee...

A p-value is associated with a test statistic. It is 'the probability, if the test statistic really were distributed as it would be under the null hypothesis, of observing a test statistic [as extreme as, or more extreme than] the one actually observed.'The smaller the P value, the more strongly the test rejects the hypothesis being tested...

The probability value (p-value) of a statistical hypothesis test is the probability of getting a value of the test statistic as extreme as or more extreme than that observed by chance alone, if the null hypothesis H0, is true.

A statistics term. A measure of probability that a difference between groups during an experiment happened by chance. For example, a P value of .01 (P=.01) means there is a 1 in 100 chance that the result of an experiment occurred by chance. The lower the P value, the more likely it is that the difference between groups was caused by treatment and ...

a measure of probability that is reported with clinical trial results. The p-value indicates the likelihood the result obtained are due to chance alone. Traditionally, a p-value of less than .05 is considered statistically significant, or not likely due to chance alone. See also confidence interval.

A measure of the strength of the evidence against the null hypothesis; the smaller the p-value, the stronger the evidence against the null hypothesis. A p-value of less than 0.05 is typically considered to indicate statistical significance. A p-value of less than 0.005 can be considered strong evidence against the null hypothesis. This is synonymou...
