for "mean absolute deviation" : Occasionally the mean deviation is defined in terms of absolute deviations from the median or other average instead of the mean. An interesting property of ... the mean deviation about the median is [that it is] a minimum. Note that it would be more appropriate to use the terminology, mean absolute deviation rather than mean deviation.  2, record 1, English, - mean%20deviation

for "average deviation" : Since the term average has a broad meaning which encompasses the arithmetic mean, the median and the mode, it is best to avoid using average and mean as synonyms.  3, record 1, English, - mean%20deviation

There are at least two reasons for measuring dispersion. The first ... is to form a judgement about the reliability of the average value. For example, if there is a large amount of scatter among the items in a series then the average size used to summarize the values may not be at all representative of the data being studied. ... a second ... is to learn the extent of the scatter so that steps may be taken to control the existing variation.  5, record 2, English, - dispersion

Les caractéristiques de dispersion les plus fréquemment utilisées sont : l'étendue, l'intervalle interquartile, l'écart absolu moyen et l'écart-type, cette dernière étant de beaucoup la plus courante. [...] L'étendue et l'intervalle interquartile sont, dans leur principe, du type de la médiane : les observations y interviennent par leur rang, et non par leur valeur. L'écart absolu moyen et l'écart-type font, au contraire, intervenir les écarts de chacune des observations à la moyenne arithmétique : ce sont des moyennes de ces écarts.  4, record 2, French, - dispersion

Moyenne arithmétique des écarts par rapport à une origine; les écarts sont pris en valeur absolue. NOTE-Généralement, l'origine choisie est la moyenne arithmétique bien que l'écart moyen soit minimal quand on prend la médiane pour origine.  2, record 3, French, - %C3%A9cart%20moyen
