Explanation: An oral thermometer may produce consistent readings, giving the measure reasonable reliability, but body temperature is not a valid…

• A. the validity of the test.
• B. an operational definition of "intelligence."
• C. the creation of a "culture fair" test.
• D. the reliability of the test.

Explanation: Giving the same test again after one month allows the psychologist to examine test-retest reliability, or the stability of scores over…

• A. functional
• B. valid

• A. Negative correlation
• B. Double-blind
• C. Content
• D. Test-retest

Explanation: Test-retest reliability checks consistency by administering the same test to the same people on two occasions and correlating the scores.

• A. Idealism; repetitiveness
• B. Repetitiveness; idealism
• C. Validity; reliability
• D. Reliability; validity

Explanation: Consistency refers to reliability, while truth or accuracy refers to validity.

• A. Split-half
• B. Test-retest
• C. Predictive
• D. Parallel forms

Explanation: Split-half, test-retest, and parallel-forms methods assess reliability, or consistency of measurement.

• A. there is a strong correlation between items on the test.
• B. it accurately measures what it says it measures.
• C. it can be used to predict future performance.
• D. they test yields similar scores if taken at two different times.

Explanation: Test-retest reliability concerns stability over time: a reliable test gives similar scores when the same person takes it on two occasions.

• A. split-half reliability
• B. test-retest reliability
• C. alternate form reliability
• D. criterion validity

Explanation: Giving the same test to the same people twice and correlating their scores measures test-retest reliability, or score stability over time.

• A. predictability
• B. reliability
• C. generalizability
• D. validity.

Explanation: Similar SAT scores across two administrations indicate high reliability, meaning the test produces consistent results.

• A. standardized
• B. normally distributed
• C. reliable
• D. valid

Explanation: Because the administrator wants to know whether test scores predict later performance at the college, he is concerned with predictive…

• A. alternate-from reliability
• B. split-half reliability.
• C. content validity.
• D. criterion reliability.Psychology

Explanation: If two versions of the same exam produce substantially different results, the exam has low alternate-form reliability.

• A. reliable; valid
• B. reliable; normal
• C. valid; reliable
• D. standardized; valid

Explanation: Validity requires consistency: a test cannot accurately measure its intended construct if its results are unreliable.

• A. evaluate how accurately test items predict a criterion behavior.
• B. derive IQ scores by comparing mental age with chronological age.
• C. extract test norms from a standardization sample.
• D. identify clusters of closely related test items

Explanation: Factor analysis examines correlations among test items and groups items that measure related abilities into clusters or factors.

• A. norms
• B. validity.
• C. reliability.
• D. stability.

Explanation: Norms provide a reference distribution from a standardization group, allowing Ana’s score of 115 to be interpreted relative to hundreds of…

• A. standardization
• B. reliability
• C. quantification
• D. psychophysics

Explanation: Standardization ensures that a test is administered, scored, and interpreted under the same conditions for everyone.
