Flashcards in INRS 7311 Learning Unit 7 Validity , Reliability , Trustworthiness and Ethics Theme 1 : Validity , Reliability and Trustworthiness in Research Deck (4):
Explain reliability in the context of quantitative research about 7 marks
*Linked to the findings of research
*Ability to produce same results using same method/instruments = reliable
*Can be loosely defined as being able to generalise results if research is repeated .
*Different types of reliability
*Interrator :different participants and same methods used
*Test/retest : Same participants and method at different times
*Parallel : Different method and/or participants at the same time
*Split halves : Different participants , same method .
Explain the concept of validity in the context of quantitative research . 5 marks
*Refers to whether or not the research measure what it was meant to .
*Do the findings reflect whats happening in the current situation ?
*Different types of validity : content/sampling validity , face validity , construct validity , criterion/instrumental validity .
Distinguish between internal and external validity . 6 marks
*Internal validity : Deals with research method and design . Can they answer the research question at hand ? Also applies to the small errors that occur within the margin or error of the research .
*External validity : Focuses on the ability to be able to generalise the research findings to the larger population . Is the researcher confident that if the research method/design is repeated on the whole population that the results would be replicated .
