The effects of such extraneous variables are depicted by the "e" or error terms in the model.

As people, for example, we all have different utility functions depending on numerous biological and extraneous variables.

That's just one example of an approach which gets away from counting events and controlling for extraneous variables.

He exhibited scientific rigor and precaution by controlling extraneous variables and leaving nothing to chance.

The participants were all separated from each other by visual barriers and precautions were taken to rule out extraneous variables.

When modeling activity or behavior, it is a conceptual tool used to limit extraneous variables such as terrain.

These extraneous variables should therefore be considered when using BPO errors as a measure.

Real life studies can best be captured by doing field studies, but it is difficult to control all extraneous variables in such studies.

This means that extraneous variables are important to consider when designing experiments, and many methods have emerged to scientifically control them.

Typically, they are considered an extraneous variable, exerting an effect on behavior other than that intended by the experimenter.
