Types of reliability Flashcards
Test-retest
repeat the same test on the same sample at a different point in time.
-> measured via temporal consistency
Parallel form
measures the correlation between two equivalent versions of a test
Inter-rater
measures the degree of agreement between different people observing or assessing the same thing.
Internal consistency
measure the correlation between items in the test that is used to measure the same construct (reliability of the measuring equipment)
Temporal consistency
The correlation between the results of the same test administered on the same sample at two different occasions (test-retest measure)
What is reliability?
The extent to which findings can be reproduced when the research is tested in the same conditions
Split half
Split the test into 2 parts, let same person completes both set then measure the consistency of result
-> used to assess internal consistency
What is needed to look out for when testing these reliabilities?
Order effects (except for inter-rater)
