All hypothesis tests ultimately use a p-value to weigh the strength of the evidence (what the data are telling you about the population). The p-value is a number between 0 and 1 and interpreted in the following way: A small p-value (typically â¤ 0.05) indicates strong evidence against the null hypothesis, so you reject the null hypothesis.
The p-value is the probability that you have falsely rejected the null hypothesis.Z scores are measures of standard deviation. For example, if a tool returns a Z score of +2.5 it is interpreted as +2.5 standard deviations away from the mean. P-values are probabilities. Both statistics are associated with the standard normal distribution.
