AQA PSYCHOLOGY: RESEARCH METHODS EXAM
QUESTIONS AND ANSWERS WITH COMPLETE
SOLUTIONS 100% VERIFIED GUARANTEED PASS
What is an independant variable?
Variable manipulated by experimenter
What is a dependant variable?
Variable measured by experimenter
What is an extraneous variable?
Variables that effect the DV other than the IV
What are 2 ways of minimising extraneous variables?
Standardised procedures, randomly assigning participants
What is a standardised procedure?
Ensure conditions set up same way apart from changing the IV
What is social desirability bias?
When people want to look good so act differently in a study
What are demand characteristics?
Participants change natural behaviour because they know it's a study
, What is a confounding variable?
Variables that vary as well as the IV
What is the difference between directional and non-directional hypothesis?
Directional - predicts direction of results
Non-directional - predicts there will be a difference between conditions
What is a null hypothesis?
States there will be no significant effect in the study
What are the types of experiments?
Laboratory, field, natural and quasi
What is a laboratory experiment?
Environment controlled by experimenter and IV manipulated
What is the evaluation for a laboratory experiment?
STRENGTH:
Have control, certain IV causes DV.
High replicability
WEAKNESS:
Demand characteristics.
Artificial environment
What is a field experiment?
In a natural setting, IV manipulated by researcher
