Validity Flashcards
What is generalisability?
If a sample is representative of a target population then we can generalise these results and conclusions to the whole target population.
What is reliability?
Being consistent
What is test-retest?
The same participants do the same measure on different occasions. There should be a high correlation between the scores.
What is inter-observer reliability?
Consistency between different observers working on the same study by using the same behavioural category checklist by there being a positive correlation between the scores when compared.
What are ways to improve reliability?
Use objective measures
Standardised method and task
What is internal validity?
Reducing extraneous and confounding variables such as demand characteristics, bias, lying, participant variables and situational variables.
What is face validity?
The measure appears to measure what it is supposed to measure.
What is concurrent validity?
The measure gets the same results when compared to the results of another established measures.
What is ecological validity?
The findings of the study can be generalised to everyday life.
What is temporal validity?
The findings of the study can be generalised from one time period to another.
