WebbThe p value is the evidence against a null hypothesis. The smaller the p-value, the stronger the evidence that you should reject the null hypothesis. P values are expressed as … WebbHowever, when covariation is considered, only the P-test and the man's age possess significant prognostic information, whereas the variables of the classical semen analysis do not. This indicates that the P-test may replace the classical semen analysis when trying to predict individual pregnancy probabilities.

WebbP-value = 0.00990 * 2 = 0.0198. That p-value is an approximation because it uses a Z-score of 2.33 rather than 2.333. Using an online calculator, the p-value for our Z test is a more precise 0.0196. This p-value is less than our significance level of 0.05, which reconfirms the statistically significant results. WebbThe p -value is a function of the chosen test statistic and is therefore a random variable.
