Statistically controlling for extraneous variables is an option for removing the influence of a variable on the study of program results.
Evaluators need to collect data on the extraneous variables, as well as the independent and dependent variables for analysis. Evaluators can use a range of statistical techniques for control including:
- General Linear Model
- Analysis of covariance
