Reliability Analysis of the AVSEO IQ Test

This study assesses the reliability of the AVSEO IQ Test as a standardized instrument. Analysis of large, diverse samples (e.g., ~266,000 participants annually for recent years like 2021-2024) drawn from our global database confirms the test's psychometric properties.

Sampling is stratified to reflect global diversity, ensuring representation from populous regions like China proportionate to their presence in our user base.

Rigorous filtering ensures data quality before analysis, removing invalid or duplicate entries. This is the same process used for our annual Global IQ Rankings by Country (Platform Data) .

Our dataset allows robust analysis representing the vast majority (>80%) of countries participating on our platform.

Exclusion of countries with very low platform participation does not significantly impact the overall psychometric validation of the test instrument itself.

The analysis consistently confirms that scores obtained on the AVSEO IQ Test follow the target normal distribution for our participant population, with a mean accurately normalized to 100 and a standard deviation of approximately 15.

Statistical validation confirms the AVSEO IQ Test provides a reliable and psychometrically sound measure of cognitive abilities relative to its standardized norms, using the Raven's Progressive Matrices method. Results are indicative within this framework and do not replace clinical assessment. Note that calculating a single worldwide IQ distribution from national averages involves different complexities and assumptions (cf. Gouillou, 2025).
