- AVerdadero
- BFalso
3Spearman's Rho is used when testing for a difference.
- AVerdadero
- BFalso
4Mann-Whitney is used when testing for a difference.
- AVerdadero
- BFalso

- AMann-Whitney
- BChi-Square
- CSpearman's Rho
- DWilcoxon
6What statistical test is used when the data is nominal?
- ASpearman's Rho
- BChi-Square
- CWilcoxon
- DMann-Whitney
7Which statistical test is used when there is an independent groups design?
- AWilcoxon
- BSpearman's Rho
- CChi-Square
- DMann-Whitney
8Which three of these apply to the Wilcoxon test?
- AData is ordinal, interval or ratio
- BData is nominal
- CUsed when testing for a difference

9Psychologists most often use a probability of 95%, so there's a 5% chance the results aren't significant.
- AVerdadero
- BFalso
10Which type of error states that the results aren't significant, when in fact they are?
- AType 1
- BType 2
11Which type of error states that the results are significant, when in fact they're due to chance?
- AType 1
- BType 2
12A one-tailed test is used in conjunction with a directional hypothesis.
- AVerdadero
- BFalso
13A two-tailed test can only be used with a non-directional hypothesis.
- AVerdadero
- BFalso
14What is a directional hypothesis?
- AA hypothesis that states the results will go a certain way, e.g. 'I predict women eat more food than men'
- BA hypothesis that states there will be a difference, but doesn't say in which way, e.g. 'I predict there will be a difference between the amount that women and men eat'
15What is a null hypothesis?
- AStates there will be a difference, but doesn't say which way results will go, e.g. 'I predict there will be a difference in the amount women and men eat'
- BStates the results will be due to chance, e.g. 'There will be no significant difference in the amount men and women eat'
16Give two strengths of lab experiments.
- AGreatest control over independent variable
- BHigher ecological validity
- CFew demand characteristics
- DControl over ethics
17Give two weaknesses of natural experiments.
- ADemand characteristics
- BNo control over extraneous variables
- CLow ecological validity
- DEthical issues
18Give one strength and one weakness of field experiments.
- AHigher ecological validity than lab studies
- BFull control over independent variables
- CLess control over extraneous variables
- DHigh risk of demand characteristics
19Demand characteristics are where the participants become aware (either consciously or subconsciously) of the aims of the study, and alter their behaviour as such.
- AVerdadero
- BFalso
20What are investigator effects?
- AAnything the investigator does which has an effect on the behaviour of participants
- BWhere the participants become aware of the aims of the study and alter their behaviour as such
- CFeatures of a research situation that alter the behaviour of participants, such as the time of day, temperature, noise levels etc.
21What is the difference between participant effects and participant variables?
- AParticipant effects is a general term to acknowledge the fact that p's behaviour can be influenced by being in a study; participant variables are characteristics of individual p's that can influence the outcome of a study
- BParticipant effects are characteristics of individual p's that can influence the outcome of a study; participant variables is a general term to acknowledge the fact that p's behaviour can be influenced by being in a study
22Single blind tests are where the participants don't know the aims of the study.
- AVerdadero
- BFalso
23Double blind tests are where the neither participants nor experimenters know the aims of the study.
- AVerdadero
- BFalso
24How can situational variables be overcome? (Give two answers.)
- AStandardisation
- BDouble blind
- CCounterbalancing
- DAnonymity
- EMatched pairs
25Order effects can be overcome using counterbalancing.
- AVerdadero
- BFalso
26Volunteer bias can be overcome using random sampling.
- AVerdadero
- BFalso
