What are the characteristics of a field experiment?

What are two strengths of a field experiment?
It is reducing demand characteristics and there is a greater ecological validity
What are two limitations of a field experiment?
It is more difficult to control variables and there is ethical issues such as privacy and deception
What are the characteristics of a natural experiment?
It is carried out in a real life setting and the IV occurs naturally
What are two strengths of a natural experiment?

What is a strength of a quasi experiment?
It is carried out in a co trolled condition
