orthogonalization

This term is primarily used in highly technical registers, specifically within linear algebra, signal processing, and statistics. In these contexts, it describes the rigorous mathematical procedure of ensuring vectors are at right angles to one another, which simplifies complex calculations by removing redundancy.

In social sciences or cognitive psychology, the term is used metaphorically to describe the conceptual separation of variables. When a researcher orthogonalizes two factors, they are attempting to strip away any shared variance so that the unique contribution of each variable can be measured without interference from the other.
