title: Talk:Mode (statistics)
text: On a more practical bent , elementary school texts are discussing the three concepts , `` mode , '' `` median , '' and `` mean '' together without even mentioning the `` average '' concept . What drew me to the mode article ( and to the section on mode , mean , and median ) was a basic exercise from my daughter 's sixth grade math text that elicits answers regarding these three particular concepts . The exercise in her homework does not discuss the concept of `` average '' or use `` mean '' interchangeably with the former term . Additionally , from a layman 's perspective , the concepts of `` mean '' or `` average '' , `` mode , '' and `` median '' are distinct concepts , not just different flavors of `` average , '' and the most common use of `` average '' does not encompass either `` mode '' or `` median '' . Otherwise , there would be confusion as to what , for example , the `` average age '' of a given population group was ( i.e. , is it the `` mode , '' `` median , '' or `` mean '' ? ) . A more in - depth treatment of the subtle differences between various `` tendencies '' is best addressed elsewhere ; the topic 's breath is somewhat greater than what most people will be searching for . -- Preceding unsigned comment added by 71.34. 165.94 ( talk ) 02 : 44 , 26 August 2008 ( UTC )
