Coverage and limits

• 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.
