Meaning of CONFOUNDING VARIABLE in English

CONFOUNDING VARIABLE

(Statistics) A variable which is associated with two or more observed variables and which directly affects the relationship between the observed variables. Often causal relationships are attributed to the observed variables when, in fact, it is the confounding variable that is the true causal factor. By holding the behavior of the confounding variable constant, the relationship between the two observed variables is no longer evident. Also see Secondary (Indirect) Association.
