econometrics

The term 'econometrics' is a modern 20th-century compound built upon the classical foundations of 'economics'. Its first element, 'eco-', originates from the Greek oikos (household), which evolved in Latin to signify estate management and later the broader system of resource management in a society. The connecting element '-nom-' derives from Greek nomos (law, custom, management), forming the core concept of 'economy' as the management of household or state resources. To this base, the scientific suffix '-metrics' (from Greek metron, measure) was appended, directly modeling the pattern of words like 'psychometrics' and 'biometrics'. Thus, the literal "measurement of economic management" logically defines the field that applies statistical and mathematical techniques to quantify and test economic relationships.
