What is the normal range of percentile?

There isn't a single "normal" percentile, as it depends on the context, but for many standardized tests and growth charts, the 25th to 75th percentile is considered the average or typical range, with the 50th percentile being the exact middle (median) where half the people score above and half below. Lower percentiles (like 10th or 25th) indicate below-average performance or smaller size, while higher ones (like 90th or 95th) show above-average results or larger size, with the key often being consistent growth or scores over time rather than hitting one specific number.
