According to the general principles of classification and definition of concepts the concepts in the course of chemical analysis addressing metrical data are sorted out, including the basic tasks of chemometrics, accuracy, precision and error. Discussions are carried out on the arrangement of contents, concept terminology and definition of some concepts in the currently popular textbooks, and relevant suggestions are put forward, in the hope of providing reference for refining the textbooks of《Chemical Analysis》and standardizing academic terminology.

Key words: Error, Accuracy, Precision, Concept classification, Operational definition
