Q

What is criterion validity?

Q

What indicates high concurrent validity?

A

Strength of correlation is +0.8 or higher

17
Q

What is predictive validity?

A

Extent to which performance on a test can predict future performance, outcomes, or behaviour

18
Q

How can internal validity be improved?

A

Demonstrating high level of control over variables

19
Q

What is random allocation?

A

A method to improve internal validity by randomly assigning participants to different groups

20
Q

What are standard procedures?

A

Consistent methods used to improve internal validity

21
Q

What is counterbalancing?

A

A technique used to control for order effects in a study

22
Q

What are single and double-blind trials?

A

Methods to prevent bias by keeping participants and/or researchers unaware of group assignments

23
Q

What is peer review?

A

A process to improve validity by having other experts evaluate the research

24
Q

What is external validity?

A

Improved by demonstrating that findings are generalisable

External validity refers to the extent to which the results of a study can be generalized to, or have relevance for settings, people, times, and measures other than the one used in the study.

25
How does replication improve external validity?
Ensures cause and effect relationship is not just limited to one experimental/observational set up ## Footnote Replication helps to confirm that the findings are consistent and reliable across different studies.
26
What effect does replicating with multiple settings have?
Improves ecological validity ## Footnote Ecological validity refers to the extent to which research findings can be generalized to real-life settings.
27
What is the impact of replicating with diverse groups?
Improves population validity ## Footnote Population validity is concerned with the extent to which findings can be generalized to and across the population.
28
What does replicating historical studies improve?
Improves temporal validity ## Footnote Temporal validity pertains to whether the findings of a study can be generalized across different time periods.
29
What is the effect of replicating using real-world tasks?
Improves mundane realism ## Footnote Mundane realism refers to how closely the materials and procedures of a study resemble the real-world situations they are intended to represent.
