WebbThe 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
