Advanced Psychology - Qp26
- 1.______ is the opposite of the experimental hypothesis and it states that the independent variable does not have the proposed effect on the dependent variable.
- A.
Variable
- B.
Experimental Hypothesis
- C.
Null Hypothesis
- D.
One and Two-tailed Hypothesis
- E.
Reliability
- F.
Validity
- 2.In most sciences, including psychology, the experiment is the most popular and desirable kind of research because it permits a direct test of a hypothesis.
- A.
True
- B.
False
- 3.Some disadvantages with the repeated measured design includes: (Select three)
- A.
Fewer subjects are needed
- B.
It is possible that taking part in one condition may affect the subject’s performance in the other conditions.
- C.
The fact that subjects are taking part in each condition at different times may affect their performance.
- D.
This design is much more sensitive to differences in the dependent variable because there isn’t the problem that these will be masked by subject differences between the conditions.
- E.
This design cannot be used in experiments where it is important that the subject does not know the purpose of experiment.
- 4.Laboratory experiments have been criticised on the grounds that the lack ecological validity.
- A.
True
- B.
False
- 5.The major disadvantage of the survey is that it may not always be possible to achieve the same level of control over the independent variables that can be achieved in the laboratory.
- A.
True
- B.
False
- 6.With a ______ type of interview the interviewer starts with a set of questions relating to the research area.
- A.
Non-directive
- B.
Informal
- C.

- 7.A way of improving the objectivity of observation is to operationalise and clearly define the behavioural categories being observed.
- A.
True
- B.
False
- 8.The ‘experimental’ approach to psychology entails conducting an intensive study of one person at a time.
- A.
True
- B.
False
- 9.Advantages of the case-study approach includes: (Select two)
- A.
The case study provides detailed information in depth about an individual, and so is the best way of predicting the behaviour of the individual subject
- B.
Results obtained with a single person cannot be used to make statements about a group.
- C.
It is a rich source for hypotheses about the causes of behaviour (whereas the experimental approach is perhaps better suited to testing hypotheses.
- 10.The major factors which determine the usefulness of a psychometric test are reliability and validity.
- A.
True
- B.
False
- 11.Correlational studies are used to test hypotheses about behaviour in cases where controlled experiments cannot be performed.
- A.
True
- B.
False
- 12.The accuracy of predictions in correlational studies depends on the extent to which the variables are correlated; a low correlation permits more accurate predictions.
- A.
True
- B.
False
