WebStandardization (Z-cscore normalization) is to bring the data to a mean of 0 and std dev of 1. This can be accomplished by (x-xmean)/std dev. Normalization is to bring the data to a scale of [0,1]. This can be accomplished by (x-xmin)/ (xmax-xmin). For algorithms such as clustering, each feature range can differ.

A ratio scale is a quantitative scale where there is a true zero and equal intervals between neighboring points. Unlike on an interval scale, a zero on a ratio scale means there is a total absence of the variable you are measuring. Length, area, and population are examples of ratio scales.

WebBy no means rely on automatic scaling. It must fit your task and data. Preprocessing is an art, and will require most of the work. Non-continuous variables are big issue. While you can "hack" data into binary encodings and then pretend they are suitable, the discreteness poses a major issue for the algorithms.
