The p-value is calculated using the sampling distribution of the test statistic under the null hypothesis, the sample data, and the type of test being done (lower-tailed test, upper-tailed test, or two-sided test). The p-value for: a lower-tailed test is specified by: p-value = P(TS ts | H 0 is true) = cdf(ts)
The P-value formula is short for probability value. P-value defines the probability of getting a result that is either the same or more extreme than the other ... |

A p-value, or statistical significance, does not measure the size of an effect or the importance of a result or evidence regarding a model or hypothesis. |
P-value is the level of marginal significance within a statistical hypothesis test, representing the probability of the occurrence of a given event. Null Hypothesis · Probability Distribution · Two-Tailed Tests · Statistical Significance |
In Statistics, P-value is defined as the measure of the probability that an observed difference might have occurred just by random chance. P-value Definition · Table · Formula |
