In a Large-Scale Study Investigating the Relationship Between Intelligence and Lifestyle

In a large-scale study investigating the relationship between intelligence and lifestyle, researchers administer a set of 10 intelligence tests which they then convert into one underlying factor. They relate this underlying factor, in turn, to various lifestyle variables such as exercise, diet, and leisure activity participation. The converted intelligence factor is known, in structural equation modeling terms, as a(n) :

A) latent variable.
B) moderator.
C) multiple factor.
D) outcome variable.
