Random Variables - Mean, Variance, Standard Deviation

WebZ-scores are also called Standard scores, z-values, normal scores, and standardized variables; the use of "Z" is because the normal distribution is also known as the "Z distribution". I believe this might be referred to as Z because the term "standard normal" means normal distribution with "zero" mean, but I may be wrong. WebTo do this, simply note that, if we take the formula for Z, multiply both sides by σ, and then add µ to both sides, we get X = Zσ+ µ 4. The interpetation of Z values is straightforward.
