A Normal distribution is described by a Normal density curve. Any particular Normal distribution is completely specified by two numbers: its mean š and its standard deviation š. The mean of a Normal distribution is the center of the symmetric Normal curve. The standard deviation is the distance from the center to the change-

Normal distribution The normal distribution is the most widely known and used of all distributions. Because the normal distribution approximates many natural phenomena so well, it has developed into a standard of reference for many probability problems. I. Characteristics of the Normal distribution • Symmetric, bell shaped

ORDER STATISTICS, QUANTILES, AND SAMPLE QUANTILES 4 For the standard normal distribution function Φ, there is no simple closed form expression for Φ itself, nor for Φ−1, although it can be computed (as in R, qnorm(p)). There are competing ways to generate a N(0,1) variable which may be preferred. Anyhow, R can generate n

With small sample sizes, the mean of the posterior distribution is a compromise between the mean of the prior distribution and the mean of the data.
