Short Research Method Evalutaion Flashcards
Evaluate independent groups design
Participants variables in yacht controlled for
Less economical and no order effects
Evaluate a repeated measures design
Order effects (use counterbalancing)
Demand characteristics
Participant variables are controlled
More economical
Evaluate a matched pairs design
No order effects
Cannot match participants exactly.
Time consuming
Evaluate lab experiments
High internal validity
Easily applicable
Low external validity (mundane realism)
Low internal validity (demand characteristics)
Evaluate field experiments
Higher external validity
Lower internal validity
Ethical issues
Evaluate the natural experiments
High external validity (real world problems)
Limited opportunities
No random allocation
Low realism
Evaluate quasi experiments.
If done in a lab, the same issues as the lab experiment
No random allocation
No manipulation of the IV
Evaluate questionnaires
Distribute too many people fix choice easy to analyse social desirability response bias
