Percentile - English Definition & Meaning

A percentile indicates the percentage of values in a dataset that fall below a specific value. 📊 Imagine you scored in the 80th percentile on a test 📝; that means you scored higher than 80% of the other test-takers. It's a way of comparing your performance to others in a group. Percentiles are often used in standardized tests like the SAT or ACT to show how you rank relative to all test-takers. They're also used in healthcare to track children's growth by comparing their height and weight to others of the same age. It's all about seeing where you stand in a crowd.
