covariates
Statistical adjustment factors
Covariates are variables that may influence an outcome in a study but aren't the main focus of investigation.
In medical research, age and weight might be covariates when testing a drug's effectiveness—factors to account for statistically rather than study directly.
The analysis controlled for covariates including income, education, and prior health conditions.
The term appears mainly in statistics and research methodology.
