PC Score Reporting and Interpretation 2

Question 1

A stanine score of 5 indicates that a test-taker performed:

Accepted Answer

In the average range relative to the norm group

Answer

Stanines range from 1 to 9, with stanine 5 representing the average band (spanning the 40th to 60th percentile of the norm group).

Question 2

What distinguishes norm-referenced interpretation from criterion-referenced interpretation?

Accepted Answer

Norm-referenced interpretation compares a score to a peer group; criterion-referenced compares to a defined performance standard

Answer

Norm-referenced interpretation locates an individual relative to others in a reference group, while criterion-referenced interpretation evaluates performance against a defined mastery standard.

Question 3

A licensing board sets a cut score of 70 on a 100-item exam. What is the primary psychometric consideration when establishing this cut score?

Accepted Answer

Balancing false positive and false negative classification errors

Answer

Cut score setting requires careful balancing of false positives (unqualified candidates passing) and false negatives (qualified candidates failing) based on the consequences of each error type.

Question 4

What does a T-score of 70 indicate in a standardized psychological assessment?

Accepted Answer

The examinee's score is two standard deviations above the mean

Answer

T-scores have a mean of 50 and a standard deviation of 10, so a T-score of 70 is exactly two standard deviations above the mean.

Question 5

A grade equivalent score of 6.4 on a reading test for a 4th grader most accurately means:

Accepted Answer

The student's raw score equals the average raw score of 6th graders in the 4th month

Answer

A grade equivalent score indicates that a student's raw score equals the median raw score obtained by students in a norm group at that grade and month level, not that the student is functioning at that grade level.
