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

The average IQ in the United Kingdom is 100.8 in our dataset of 1,134 test results. See the full distribution, confidence interval, and how the United Kingdom compares worldwide.

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.
