Field experiment


core definition

A field experiment is one that takes place outside the laboratory but in which the experimenter is able to allocate subjects to different treatment groups at random.


explanatory context

The experiment takes place in an otherwise natural or field setting.

 

This may be done, for example, to study the effects of specified policy changes or of a goverment publicity campaign.

 

By contrast, in a quasi-experiment the researcher is not able to allocate subjects to different treatment groups randomly, and is restricted to groups that occur naturally.


analytical review

Holah (2009) wrote:

An experiment which is carried out in ‘the field ’. That is, in a real world situation.

In field experiments the participants are not usually aware that that they are participating in an experiment. The independent variable is still manipulated unlike in natural experiments.

Field experiments are usually high in ecological validity and may avoid demand characteristics as the participants are unaware of the experiment.

However in field experiments it is much harder to control confounding variables and they are usually more time consuming and expensive.

In field experiments it is not usually possible to gain informed consent from the participants and it is difficult to debrief the participants.
