This is the process of demonstrating that there is a statistical relationship between scores of a measure and an outcome variable of interest (like job success).

a. Test-retest reliability

b. Construct related validity

c. Internal consistency reliability

d. Criterion related validity

e. Content related validity

The correct answer and explanation is:

Correct Answer: d. Criterion related validity

Explanation (300 Words):

Criterion-related validity refers to how well one measure predicts an outcome based on another established or known measure (the “criterion”). In other words, it’s a way to demonstrate that a test or assessment is statistically related to an important outcome — like job performance, academic success, or customer satisfaction.

There are two types of criterion-related validity:

1. Predictive validity – when the test is used to predict future performance.
   Example: Using a college entrance exam score to predict a student’s future GPA.
2. Concurrent validity – when the test and the criterion are measured at the same time.
   Example: Correlating a current employee’s job performance rating with their results from a new aptitude test.

In the question, the phrase “demonstrating a statistical relationship between scores of a measure and an outcome variable of interest (like job success)” directly refers to criterion-related validity, since it involves linking test scores to a real-world performance measure.

Why the Other Options Are Incorrect:

• a. Test-retest reliability measures the stability of test scores over time, not their relationship with outcomes.
• b. Construct-related validity assesses whether a test measures the theoretical construct it’s intended to (e.g., intelligence, motivation).
• c. Internal consistency reliability checks how consistently items on a test measure the same construct, not how they relate to an external criterion.
• e. Content-related validity evaluates whether the test content represents the entire range of the subject or behavior it’s supposed to measure (e.g., does a math test cover all relevant topics?).

Conclusion:

Criterion-related validity is the correct answer because it directly addresses the concept of correlating test results with a specific outcome — like job success — using statistical methods.
