What does reliability mean in psychological research?
the consistency
Reliability refers to the consistency of a measure. 1 A test is considered reliable if we get the same result repeatedly. For example, if a test is designed to measure a trait (such as introversion), then each time the test is administered to a subject, the results should be approximately the same.
What is external reliability?
the extent to which a measure is consistent when assessed over time or across different individuals.
Why is external reliability important?
External reliability This assesses consistency when different measures of the same thing are compared, i.e. does one measure match up against other measures? Discrepancies will consequently lower inter-observer reliability, e.g. results could change if one researcher conducts an interview differently to another.
Is ageing intrinsic or extrinsic?
Intrinsic ageing is an inevitable, genetically determined process that occurs naturally and is affected by the degenerative effects of free radicals, hormonal shifts and the body’s inability to perfectly repair skin damage1. Extrinsic ageing, on the other hand, is a result of lifestyle and environmental factors1.
What is external reliability and example?
External reliability means that your test or measure can be generalized beyond what you’re using it for. For example, a claim that individual tutoring improves test scores should apply to more than one subject (e.g. to English as well as math).
What is the difference between internal and external validity?
Internal validity refers to the degree of confidence that the causal relationship being tested is trustworthy and not influenced by other factors or variables. External validity refers to the extent to which results from a study can be applied (generalized) to other situations, groups or events.
