WebSep 5, 2024 · For this, we will use the fact that the total area under the normal Z distribution is 1. Therefore the area to the right of Z-score (or p-value represented by the unshaded region) can be calculated as: p-value = 1 – 0.999. p-value = 0.001. 0.001 (p-value) is the unshaded area to the right of the red point. WebThe p-value is a probability. For the pattern analysis tools, it is the probability that the observed spatial pattern was created by some random process. When the p-value is very small, it means it is very unlikely (small probability) that the observed spatial pattern is the result of random processes, so you can reject the null hypothesis.
