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.
