The mean absolute difference is a measure of statistical dispersion equal to the average absolute difference of two independent values drawn from a probability distribution. A related statistic is the , which is the mean absolute difference divided by the arithmetic mean, and equal to twice the Gini coefficient.The mean absolute difference is also known as the absolute mean difference (not to be confused with the absolute value of the mean signed difference) and the Gini mean absolute difference. The mean absolute difference is sometimes denoted by Δ or as MD.

Property Value
dbo:abstract
  • En statistiques, l'écart moyen est une mesure de la dispersion. Il se calcule ainsi : * dans le cas d'une série discrète non triée, écart moyen = ; * dans le cas d'une série discrète regroupée, écart moyen = ; * dans le cas d'une série continue, écart moyen = . (fr)
  • La differenza media assoluta è una misura di variabilità, ovvero una misura che mette in evidenza la disuguaglianza dei dati tra loro, indipendentemente da qualsiasi valore medio. È chiamata anche differenza media (semplice) di Gini, si indica con Δ ed è data dalla media aritmetica dei moduli degli scarti di ciascun valore da tutti i rimanenti. Si calcola come segue:Metodo diretto: con i≠jMetodo alternativo: (it)
