3 important questions on Experimental field research - The basics of experimental field research
How do field experiments differ from lab experiments?
Field experiments are carried out in the everyday, real-life environment of the participants. As in lab experiments the researcher manipulates the independent variable but the:
- Setting
- participants
- manipulations / treatments
- outcome measures
What are the characteristics of a field experiment?
- Randomized experiment in a real-word setting
- Results are generalizable to real-world behavior
- Participant are unaware taht they are taking part in a study and are unaware of the different manipulations
- Often requires to work together with an organization
- Tranditional (offline) field experiments v.s. Large-scale (online) field experiments
When to use field experiments?
- When the number of independent (and moderator) variables is limited and when they can be manipulated
- When it is important to measure real-world behaviro in real-world situations (high external validity is curcial)
- When you want to capture second-order and long-term effects of your manipulations
The question on the page originate from the summary of the following study material:
- A unique study and practice tool
- Never study anything twice again
- Get the grades you hope for
- 100% sure, 100% understanding
Remember faster, study better. Scientifically proven.
