AICE Psychology Paper 2
Exam Questions with Answers
1. ecological validity Correct Answer: The extent to which a study is realistic or representative
real life.
2. mundane realism Correct Answer: the extent to which experimental findings can be
generalized to the real world
3. internal validity Correct Answer: How well is the experiment done? less confounding
variables = higher
4. external validity Correct Answer: validity of applying the conclusions of a study outside the
context of the study
5. generalze Correct Answer: can the study be related to a large group of people?
6. inter-rater reliability Correct Answer: measure of agreement among observers on how they
record and classify a particular event
7. Reliablility Correct Answer: how consistent are the scores of the study or experiment?
8. Correlation Correct Answer: measure of the extent that two variables are related
9. statistical significance Correct Answer: when the result is highly unlikely to have occurred
given the null hypothesis
10. Independent measures design Correct Answer: Using DIFFERENT participants in
each condition of the experiment, each participant only sees one level of the IV
11. repeated measures design Correct Answer: The same participants are used in al
the conditions in an experiment
12. matched pairs design Correct Answer: when the participants are matched on a
variable (bandura et al participants were matched on aggression levels)
13. null hypothesis Correct Answer: a hypothesis that states there is no statistical
significance between two variables
14. one-tailed hypothesis Correct Answer: statistical test in which the critical area of
distribution is one sided (females will score higher on the eyes test than males)
15. two-tailed hypothesis Correct Answer: both directions of an ettect or relationship

, are considered in the alternative hypothesis of the test (basically gives two options instead of
telling us only one)
16. Nature vs. Nurture Correct Answer: debate on whether human behavior is
determined by the environment (nurture) or by a person's genes (nature)
17. Ethics for humans Correct Answer: need consent, no harm may be done, participant
MUST leave in the same state they arrived, psychological state MUST stay in tact
18. correlation coefficient Correct Answer: measure of the direction and extent of the
relationship between two scores
19. measures of central tendency Correct Answer: mean, median, mode
20. Measures of Variance Correct Answer: range, interquartile range, variance,
standard deviation
21. standard deviation Correct Answer: measure of variance that indicated typical
distance between the scores of a distribu- tion and the mean, low standard deviation is good bc it
shows that the data is not widespread and it is more reliable
22. Volunteer sampling Correct Answer: When participants put themselves forwards to
take part in the investigation e.g. respond to an advert
