The smaller the p-value, the higher the significance, and the more evidence there is that the null hypothesis should be rejected for an alternative hypothesis. In other words, determining a p-value helps you determine how likely it is that the observed results actually differ from the null hypothesis. Assuming that the given null hypothesis is correct, a p-value is the probability of obtaining test results in an experiment that are at least as extreme as the observed results.
In statistical hypothesis testing, the null hypothesis is a type of hypothesis that states a default position, such as there is no association among groups or relationship between two observations.
Z-scoreĪ p-value (probability value) is a value used in statistical hypothesis testing that is intended to determine whether the obtained results are significant. Please provide any one value below to compute p-value from z-score or vice versa for a normal distribution. Home / math / p-value calculator P-value Calculator
