Brain Wave Collection Series. Chapter 3 -The Technical Background, Part 1 -Standard Deviation

Part 1: Precision analysis is required whenever data sets are available.

Looking for errors and omissions, and performing statistical analysis is at the heart of QEEG clinical interpretation. You will get a brief introduction to stats without math formulas.
