Webb10 aug. 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 μ and the standard deviation σ. WebbChapter 8 The Normal Distribution 155 8.2 The p.d.f. of the normal If you could work in only whole numbers of SDs, the number of problems that could be solved would be limited.
