PC PC Test Development and Validation 2

Question 1

Criterion-related validity evidence is obtained by:

Accepted Answer

Correlating test scores with an external measure of the same construct

Answer

Criterion-related validity is established by statistically correlating test scores with a relevant external criterion, such as job performance ratings.

Question 2

In test development, which item format is most susceptible to guessing, potentially inflating scores?

Accepted Answer

True/False

Answer

True/False items have a 50% probability of a correct guess by chance, making them the most susceptible to guessing among common item formats.

Question 3

Test equating in large-scale psychometric programs is performed to:

Accepted Answer

Ensure that scores from different test forms are comparable

Answer

Test equating adjusts scores across multiple test forms so that a given score reflects the same level of ability regardless of which form was administered.

Question 4

Which principle of test development requires that instructions, administration conditions, and scoring procedures be identical for all examinees?

Accepted Answer

Standardization

Answer

Standardization ensures that all examinees experience the same testing conditions, making scores meaningful and comparable across individuals.

Question 5

Convergent validity evidence for a new psychometric instrument is demonstrated when:

Accepted Answer

The instrument correlates highly with established measures of the same construct

Answer

Convergent validity is supported when the new measure correlates strongly with other measures theoretically designed to assess the same or similar constructs.
