Chapter 7 Flashcards
What are two problems with an field experiment?
Problems with randomization.
Problems to exclude external influences.
What is an field experiment?
Randomized experiment in a real-world setting.
What is meant with field research provides authenticity?
Field experiments provide authentic context, treatments, participants and outcomes.
What is meant with field research provides novel isnights?
Field experiments enable to answer questions that cannot be answered in the lab.
What are disadvantages of field experiments?q
Time consuming, Challeging to implement, Focus on observed behavior High degree of noise Ethical consideration.
What is poor timing & unexpected situational factors?
Changes in environment unreleated to the study.
What is failure to randomize?
No randomization of participants.
What is non compliance?
Subjects that are supposed to receive treatment do not receive it.
What are spillover & side effects?
One participant is affected by the treatmetn of others.
What is insufficient sample size?
Insufficient power to detect effects.
What is reliability of measures?
For concrete constructs, single item.
For abstract constructs, multi item (use cronbach).
What is A/B testing?
Field experiment,
Testing on large-scale
Results scale easily
Focus on Conversion Rate.
Where is A/B testing good at?
Replacing intuition with tests.
Small changes can have big impacts.
Name three advantages of experimental research?
Real-world behavior
Authenticity
Novel insights.
Which threats does field experiments have for internal validity?
Poor timing & unexpected factors, Failure to Randomize, Non-compliance Spillover & side effects Insufficient sample size
