VALIDITY Flashcards
the degree in which evidence and theory support the interpretations of test scores entailed by the proposed uses of the tests
validity
not an adequate representation of the construct
construct underrepresentation
test measures characteristics, or kills that are unrelated to the test construct
construct-irrelevant variance
refers to the appropriateness or accuracy of the interpretation of test scores
validity
the degree to which
evidence and theory support the interpretations of test
scores entailed by the proposed uses of the tests
validity
involves how adequately the test samples the content
area of the identified construct –
content validity
examining the relationships between the test
and external variables that are thought to be direct
measures of the construct
Criterion-related Validity
an integration of evidence that relates to the
meaning or interpretation of test scores
Construct Validity
Sources of Validity Evidence
TEST CONTENT RELATIONS TO OTHER VARIABLES INTERNAL STRUCTURE RESPONSE PROCESSES CONSEQUENCES OF TESTING
a test “appearing” to measure what it is
designed to measure
Face Validity
Examining different groups
which are expected based on theory to differ on the
construct the test is designed to measure
Contrasted Group Studies
Test, time interval, criterion is measured
Predictive studies
Test is administered and criterion is
measured at the same time
Concurrent studies
when you correlate a test with existing tests
that measure the same or similar constructs
Convergent:
when you correlate a test with existing tests
that measure dissimilar constructs
Discriminant
