WebDec 13, 2024 · In statistical hypothesis testing, the p-value (probability value) is a probability measure of finding the observed, or more extreme, results, when the null hypothesis of a given statistical test is true. The p-value is a primary value used to quantify the statistical significance of the results of a hypothesis test. WebThe negative coefficient indicates that for every one-unit increase in X, the mean of Y decreases by the value of the coefficient (-0.647042012003429). Your p-value is displayed using scientific notation. You need to move …

WebThe 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 actual observations. The P-value represents the probability of occurrence of the given event. The formula to calculate the p-value is: Z = ^p−p0 √p0(1−p0) n Z = p ^ − p 0 p 0 ( 1 − p 0) n
