Imagine being in a bustling city for the first time. The streets are filled with people moving in every direction, buildings tower above you, and everything seems to blend into a chaotic blur. It’s overwhelming—until you start to notice patterns. People seem to be heading toward specific landmarks, traffic moves in predictable flows, and soon enough, the city starts to make sense. You begin to see the structure that was hidden beneath the surface noise. That’s what factor analysis does for data. It helps you find the underlying patterns in what seems like a maze of variables and relationships, uncovering the order in apparent chaos.This book was written out of a fascination with how data, no matter how overwhelming, can reveal its secrets if you know where to look.
