Students of statistics and probability theory sometimes develop misconceptions about the normal distribution, ideas that may seem plausible but are mathematically untrue. For example, it is sometimes mistakenly thought that two linearly uncorrelated, normally distributed random variables must be statistically independent.

DEFINITION:Random variable A is said to be normal, denoted A ∈ ƒ, when its sample observations follow a univariate or multivariate Gaussian distribution of some fixed mean and (co)variance; when making statements about more than one multivariate random variable, e.g. three multivariate random variables A ∈ ƒ, B ∈ ƒ, C ∈ ƒ, then ...
The simplest case of a normal distribution is known as the standard normal distribution or unit normal distribution. This is a special case when μ = 0 {\textstyle \mu =0} and σ 2 = 1 {\textstyle \sigma ^{2}=1} , and it is described by this probability density function (or density): φ ( z ) = e − z 2 2 2 π . {\displaystyle \varphi (z ...
