Webb16 juli 2024 · The p value is a number, calculated from a statistical test, that describes how likely you are to have found a particular set of observations if the null hypothesis were true. P values are used in hypothesis testing to help decide whether to reject the null hypothesis. The smaller the p value, the more likely you are to reject the null hypothesis. WebbUsually in statistics, Φ (x) is used to denote the Cumulative distribution function of standard normal random variable (Normal random variable with mean 0 and variance 1).
