Reliability Flashcards
What is reliability
Consistency of measurements
How is reliability of observations assessed
With inter-observer where the reliability should be greater than 80
How can observation reliability be improved
it is improved by better operationalisation of behavioural categories by training observers
How is the reliability of self-report assessed
With test retest: repeat test with same participants over short interval of a few weeks
How is self-report reliability improved
By reducing ambiguity in questions
How is the reliability and experiments assessed
May relate to how the DVD is measured e.g. using observations or Self Report
How can an experiment reliability be improved
Using standardisation of procedures in order to be able to repeat method with all participants
