Based on the UniversalIQTest.com online dataset (Passed quality checks / All results)

In our online dataset, Czechia's IQ-style group score is 99.3 from 1,474 results. See sample size, distribution and age/gender breakdowns.

These are averages from self-selected participants in the UniversalIQTest.com online test (not population IQ).

Use N and Approx. interval when comparing; avoid causal conclusions.

The displayed group score converts the group’s average percentile rank in the selected dataset view to an IQ-style scale (100, standard deviation 15). It is not the arithmetic mean of individual IQ scores.

Intervals use an approximate spread estimated from the interquartile range and sample size. They are indicative uncertainty ranges around the transformed group score, not validated confidence intervals for a population mean.
