In a field experiment, what is a primary feature?

The primary feature of a field experiment is that it takes place in a familiar setting for participants. This environment can be a natural setting that reflects the participants' everyday experiences, which enhances the ecological validity of the research. Unlike laboratory experiments, where the setting can be artificial and may influence behavior, field experiments aim to observe how participants act in real-world scenarios. This allows researchers to study genuine reactions and behaviors in a more relatable context, which is particularly valuable in psychological research.

Options that suggest all variables are uncontrolled, complete control over conditions, or exclusive collection of qualitative data do not accurately represent field experiments. While field experiments may have some level of control, they generally allow for some uncontrolled variables, as they are conducted in natural environments. Moreover, field experiments can collect both qualitative and quantitative data, not exclusively one type.
