Assessment and Testing Flashcards

A counselor administers the same test to a client twice within two weeks and obtains very different scores. This most likely indicates a problem with which psychometric property?

Answer: Test-retest reliability

Test-retest reliability refers to the consistency of scores across repeated administrations over time, so large score differences indicate poor test-retest reliability.

Which type of score indicates what percentage of individuals in the normative sample scored at or below a given raw score?

Answer: Percentile rank

A percentile rank indicates the percentage of people in the norm group who scored at or below that particular score.

When a test measures what it claims to measure, it is said to have:

Answer: Construct validity

Construct validity refers to how well a test actually measures the theoretical construct it was designed to assess.

A counselor uses a career interest inventory to predict job satisfaction five years later. This is an example of assessing:

Answer: Predictive validity

Predictive validity examines how well a test score forecasts a future criterion, such as job satisfaction measured years later.

In norm-referenced testing, a student's score is compared to:

Answer: The performance of a standardized sample group

Norm-referenced tests interpret an individual's score relative to the performance of a normative or standardization sample.

Which statistical concept describes the spread of scores around the mean in a normal distribution?

Answer: Standard deviation

Standard deviation quantifies the average amount that scores deviate from the mean, reflecting the spread of the distribution.

A counselor notices that a personality inventory has questions that appear relevant to the trait being measured. This describes:

Answer: Face validity

Face validity refers to whether a test appears, on its surface, to measure what it intends to measure, without empirical verification.
