CE ÎNSEAMNĂ CENTRAL TENDENCY ÎN ENGLEZĂ?
Tendința centrală
În statistici, o tendință centrală este o valoare centrală sau o valoare tipică pentru o distribuție a probabilităților. Este uneori numită o medie sau doar centrul distribuției. Cele mai comune măsuri ale tendinței centrale sunt media aritmetică, mediana și modul. O tendință centrală poate fi calculată fie pentru un set finit de valori, fie pentru o distribuție teoretică, cum ar fi distribuția normală. Ocazional, autorii folosesc tendința centrală de a însemna "tendința datelor cantitative de a clustera în jurul unei valori centrale". Acest înțeles ar putea fi așteptat de la definițiile uzuale ale dicționarului pentru tendința și centralizarea cuvintelor. Acești autori pot să decidă dacă datele au o tendință centrală puternică sau slabă bazată pe dispersia statistică, măsurată prin deviația standard sau ceva similar. Termenul "tendință centrală" datează de la sfârșitul anilor 1920.
