Distorting variable in research
A factor in a study that can make the results misleading because it is connected to both the cause being studied and the result.
Usage pattern:
[variable/factor] is a confounder; control for/adjust for confounders
Common mistake:
Do not confuse a confounder with any variable in a study; a confounder specifically distorts the relationship being analyzed.
Synonyms
confounding variable (A fuller, very common technical term for the same idea.)

confounding factor (Slightly broader; often used when the confounder is not strictly numerical.)
|
lurking variable (Used especially in statistics education for a hidden or unconsidered confounder.)
