Normal probability distribution curve
WebThe way I understand it, the answer choice would have to explicitly state "The percentage of data below/above the mean/standard deviation" as opposed to "The mean/standard deviation".In a standard normal distribution, the mean (µ) by itself is equal to 0, and the standard deviation (σ) is equal to 1. We know this because normal distributions are … Web1 de jul. de 2024 · The normal distribution, which is continuous, is the most important of all the probability distributions. Its graph is bell-shaped. This bell-shaped curve is used in almost all disciplines. Since it is a continuous distribution, the total area under the curve is one. The parameters of the normal are the mean \(\mu\) and the standard deviation σ.
