This document provides an overview of chemometrics. It begins with defining chemometrics as using mathematical and statistical methods to design experiments and analyze chemical data. The history of chemometrics is then discussed, noting it was coined in 1971 and the International Chemometrics Society was formed. Various chemometric techniques are described like multivariate calibration, pattern recognition, and multivariate curve resolution. Applications include exploratory analysis, regression analysis, and classification of data. Careers in chemometrics extend beyond chemistry to fields like biochemistry and medicine.
