IQ Statistics
Analyze the trends and average results observed.
IQ scores generally follow a normal distribution centered on 100, with a standard deviation of about 15.
In practice, most scores fall between 85 and 115, reflecting the natural variability of cognitive abilities.
Statistical analyses take into account factors such as age, education level, test language and cultural context.
Our reports compare your result with reference cohorts to give you a clear, nuanced picture of where you stand.
Longitudinal trends show how averages evolve and identify the most common areas for improvement.
Analyses by sub-domain (verbal, logical, spatial, memory) give a more detailed view than the overall score.
These statistics are used to adjust test difficulty, ensure fairness and improve assessment accuracy.
