A quality of a measure concerning how dependable it is
reliability
A quality of a measure concerning how accurate it is
validity
_______ is not necessarily about being correct but instead about being stable and predictable
reliability
A variable that averages a set of items (typically from a survey) to measure some concept
composite variable
Reliability: the degree to which a set of various items in a composite variable lead to a consistent response and, therefore, are tapping into the same concept
internal reliability
Reliability: internal reliability considers the degree to which individuals respond to items in a ________ way
consistent
Reliability: this type reveals how much different coders or observers agree with one another when looking at the same data
intercoder reliability
Reliability: intercoder reliability is also called ___________ reliability
inter-observer
A quality of an operational protocol referring to how well it works
robustness
Reliability: a method of testing robustness in which the similarity of results is assessed after administering a measure to. the same sample at two different times
test-retest
Reliability: the test-retest method assesses whether a measure is consistent over _______-timeReliability: a method of testing robustness in which the similarity of results is assessed after administering one subset of an item to a sample and then another subsetsplit-halfReliability: the process of administering some measurement protocol to a small preliminary sample of subjects as a means of assessing how well the measure workspilot testingThe degree to which a study establishes a causal effect of the independent variable on the dependent variableinternal validity of a studyThe degree to which a measure truly and accurately measures. the defined conceptinternal validity of a measureValidity: a dimension of validity concerning whether a measure looks validfaceValidity: your measure closely matches a pre-existing measure of the same concept, at the same time, that is already known to be validconcurrentValidity: a dimension of validity concerning how strongly a measure correlated with a measure that it should predictpredictiveValidity: in predictive validity, the measure correctly predicts scores on a criterion that will only be available in the ________futureValidity: a dimension of validity concerning how well a measure encompasses the many different meanings of a single conceptcontentValidity: in content validity, a measure must capture all of the _________ of a conceptdimensionsValidity: a dimension of validity concerning how well multiple indicators are connected to some underlying factorconstructValidity: construct validity applies when the concept being measured is _________, like depressionintangibleValidity: ____________ validity is about whether the responses capture the unobservable conceptconstruct
