Talk:Intervening variable

This page seems very confusing to me. It seems like all 3 paragraphs were written by different people with little attempt to make the transitions smooth. We are talking about hunger and then all of a sudden we're discussing racism. Bizarre.

The section regarding examples of intervening variables is consistent with the distinction made between hypothetical constructs and intervening variables on the Hypothetical Constructs page http://en.wikipedia.org/wiki/Hypothetical_construct. —Preceding unsigned comment added by Existential zombie (talk • contribs) 20:51, 30 November 2009 (UTC)

A synonym - "mediator variable"
In statistics there is a synonym for intervening variable - "mediator variable". See Mediation (statistics). It seems that some crossreferences or merging needed. —Preceding unsigned comment added by 90.189.181.244 (talk) 17:38, 5 March 2011 (UTC)

Intervening varable can be either mediator or moderator, which is aimed to better explain the relationship between Independent variable and dependent variable. by xiaoqiangbaobao ustc 2011 3 27
