How We Calibrate Your Scoring Matrix
Online diagnostic tools shouldn't be dynamic guesses. Our analytical matrix framework ensures structural calibration based on proven statistical models.
Fluid Reasoning Index (Gf)
We target spatial abstractions, patterns, and directional dynamics. These minimize cultural, language, and educational biases, keeping standard measurements highly pure.
Statistical Variance Tuning
Evaluations are balanced using standard deviation settings (SD = 15), allowing direct mapping against traditional clinical tests like the WAIS-IV.
Global Normative Database
Your response speed and pattern precision are compared against a dataset comprising over 1.4 million logged metrics across multiple age brackets.
Free Assessment vs Certified Profile
We keep diagnostic entries open. Real statistical validation requires the full certified assessment path.
