Interpretation of field experiment terms

Field experiment is a simulation experiment conducted at the crime scene, the purpose of which is to determine under what conditions an event will occur, or whether and how an event will occur under given conditions.

In the field experiment, researchers will deeply study the living and working environment of the subjects, collect data through observation, interviews and questionnaires, and explore the nature and laws of social phenomena through the analysis of the data. Because the field experiment is carried out in the real life environment, it can reflect the real situation of social phenomena more accurately and explore the causal relationship between social phenomena.

The advantage of field experiment lies in its high ecological validity, that is, the experimental results can be better applied to real life environment. In addition, field experiments can also explore the complex relationship between social phenomena and explore the causal relationship through intervention. However, the field experiment has some shortcomings, such as high controllability and repeatability, and the experimental results are easily influenced by other factors.

The difference between field experiment and traditional experiment;

1, different experimental environments. Traditional experiments are usually carried out in artificial environments, such as laboratories or specific experimental sites, and all variables can be strictly controlled and manipulated by researchers. However, the field experiment is carried out in real life environment, and researchers cannot completely control all external variables, so the ecological validity of the experiment is higher.

2. The research purposes are different. Traditional experiments are usually to test a specific hypothesis or theory, and all variables can be strictly controlled and manipulated to verify the correctness of the theory. However, the purpose of field experiments is usually to explore the phenomena or problems in the real world, and pay more attention to observation and experiments in the natural state to reveal the causal relationship between phenomena.

3. The replication and generalization of the experiment are also different. Because the traditional experiment is carried out in an artificial environment, all variables can be strictly controlled, so it is easier to copy and verify. However, the field experiment is carried out in real life environment, and it is difficult to completely replicate. The experimental results are more general and can be better applied to real life.
