Class 5 Flashcards
Is it reliable?
- replicability
- is it a consistent test/measure?
Test-retest reliability
- consistency in results
- important in personality research
- state personality VS trait personality
Internal consistency reliability
- internal consistency
- consistency in a pattern of answers, no matter how the question is phrased
Inter-rater reliability
- degree to which 2+ coders/observers give a consistent rating of a set of targets
- important in observational research
Is it valid?
Is it an accurate measure?
Does it measure what we want it to measure?
RELIABLE DOES NOT MEAN VALID
Construct validity
how well is the variable measured or manipulated
Face validity (construct)
Does it look like a good measure (subjective)
Content validity (construct)
The measure contains all the parts that established theory says it should (subjective)
Criterion validity (construct)
Predictive validity, measure is correlated with a relevant outcome (empirical)
Convergent + discriminative validity (construct)
- convergent: measure is strongly associated with measures of similar constructs (empirical)
- discriminant: measure is not strongly associated with measures of dissimilar constructs (empirical)
Statistically conclusive validity
When the conclusions of a research study are founded on an adequate analysis of the data
Internal validity
- are the results valid?
- are they effected by controlling the environment of study?
External validity
- generalizability
- how well do the results from one area apply to another area
