Crash course in psychometric testing - Module 3: Reliability, Validity and Norms

The video discusses the importance of psychometric properties in measuring complex psychological characteristics. The three main psychometric properties are:

Reliability: Measures how consistent the test is in measuring across multiple times.
Validity: Ensures that the test is really measuring what it claims to measure, especially important for intangible and complex attributes.
Norms: Provides a reference point for comparison to determine if a score is low, medium, or high.
The video explains that these properties are crucial in psychometric tests, as they provide confidence in their proper use, especially when decisions about people are made based on test results.

Key Takeaways:

Psychometric properties are essential for measuring complex psychological characteristics.
Reliability measures consistency across multiple administrations.
Validity ensures the test is measuring what it claims to measure.
Norms provide a reference point for comparison of scores.
