P value explained simply
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. WebIn statistics, a p-value is the probability that the null hypothesis (the idea that a theory being tested is false) gives for a specific experimental result to happen. p-value is also called probability value. If the p-value is low, the null hypothesis is unlikely, and the experiment has statistical significance as evidence for a different theory.
