WebNov 5, 2024 · The standard normal distribution is a probability distribution, so the area under the curve between two points tells you the probability of variables taking on a range of values. The total area under the curve is 1 or 100%. Every z score has an associated p value that tells you the probability of all values below or above that z score occuring. Webⅇ- (x-μ)2 2σ2 2πσ It turns out that again about 95% of the time an observation from a normal distribution will be within two standard deviations from the mean.
