The p-value
Webb30 aug. 2024 · Suppose we would like to find the probability that a value in a given distribution has a z-score between z = 0.4 and z = 1. Then we will subtract the smaller value from the larger value: 0.8413 – 0.6554 = 0.1859. Thus, the probability that a value in a given distribution has a z-score between z = 0.4 and z = 1 is approximately 0.1859. Webb9 dec. 2024 · p-value definition and meaning.
