UPDATED QUESTIONS AND CORRECT
ANSWERS
CONTENT validity - CORRECT ANSWERS✅✅the assessment measures the content it's
designed to assess
Purpose of CONSTRUCT validity - CORRECT ANSWERS✅✅Checks to see if test
measures what it's supposed to and not something else
Purpose of CONTENT validity in objective assessment - CORRECT ANSWERS✅✅To
determine how closely the test represents what should be assessed.
Objective assessment - CORRECT ANSWERS✅✅Question with only one answer
Purpose of CRITERION-RELATED validity - CORRECT ANSWERS✅✅Measures the
degree of correlation between a first and 2nd test
CONSEQUENTIAL validity - CORRECT ANSWERS✅✅results are used for a purpose and
have social significance.
FACE validity - CORRECT ANSWERS✅✅looks valid on the surface
CONSTRUCT validity - CORRECT ANSWERS✅✅Degree to which a test actually
measures what it claims to measure
CRITERION-RELATED validity - CORRECT ANSWERS✅✅Validity is determined by
comparing one test to another (2 types: concurrent & predictive)
PREDICTIVE validity - CORRECT ANSWERS✅✅results used to determine future
achievement
, CONCURRENT validity - CORRECT ANSWERS✅✅the extent to which two measures of
the same trait or ability agree
OR
how well a new test compares to a well-established test
How do you ensure validity of a test? - CORRECT ANSWERS✅✅1. Scoring procedures
are evaluated for objectivity FAIRNESS
