Experimental vs Non-Experimental
A study that manipulates variables and uses random assignment is called what?
Experimental design
The variable that is manipulated is the:
Independent variable
Accuracy of measuring what you intend to measure:
Internal validity
Assigning participants by chance:
Random assignment
Participants must agree after understanding risks:
Informed consent
A study that observes variables without manipulation is called what?
Non-experimental research
The variable being measured is the:
Dependent variable
Ability to generalize results to the real world:
External validity
Keeping all participants treated the same:
Standardization
Protecting identity and personal data:
Confidentiality
Why is experimental design stronger for conclusions?
It allows cause-and-effect conclusions
A variable that may influence results if not controlled is called:
Confounding variable
When another factor explains the results, validity is threatened by:
Confounds
Comparing groups with and without treatment:
Control group
When researchers explain the true purpose after the study:
Debriefing
