Definitions
In plain terms
A z-score of 1 means the observation is one selected standard deviation above the selected mean.
Technical
The conventional z-score subtracts the population or sample center and divides by a nonzero scale, with explicit cross-section, winsorization, grouping, and missing-value rules.
Scope
Standardization does not make a distribution normal or remove outliers automatically.
Formula
z = (x - mu) / sigmaz=(x-\mu)/\sigma| Symbol | Meaning | Unit |
|---|---|---|
x | observed value | input unit |
mu | declared center | input unit |
sigma | declared positive scale | input unit |
Output unit: standard deviations
Examples
- A governed methodology records standardized score with its source, cutoff, units, parameters, and effective version.
Common misconceptions
- Standardized Score does not have one universal implementation without the declared methodology, data basis, and constraints.
