What does normalize mean?
Normalize means to bring something into a standard, regular, or consistent form. The word is especially common when discussing spelling, data, measurements, formatting, and comparisons: values may be normalized so that different units or ranges can be evaluated together. In mathematics and statistics, normalization often means converting figures to a common scale, such as a standard range or unit. In broader contexts, normalize can mean restoring something to an ordinary, stable, or expected condition, as in normalizing a process or relationship. The term is generally neutral, although in technical work it can carry the implication that variation is being reduced or removed. This may be useful for making comparisons consistent, but it can also obscure meaningful distinctions if the original differences are important. The word is spelled normalize in American English and normalise in British English.
