Normal Distribution Gaussian Normal random variables

Normal Distribution Gaussian Normal random variables normal distribution The sampling distribution of the mean becomes approximately normal regardless of the distribution of the original variable The sampling distribution of the normal distribution This is the unshaded part of the graph from the mean to x 1 x 1 This is a normal distribution curve A value, x, is labeled on the Figure

normal distribution If a set of n observations is normally distributed with variance σ2, and s2 is the sample variance, then s2σ2 has a chi-square distribution with n–1

normalization The normal distribution , also referred as bell curve, is very useful due to the central limit theorem Normal distribution states 2 The mean, median, and mode are equal The middle point of a normal distribution is the point with the maximum frequency, which means that it possesses the
