Percentile rank shows the percentage of data points below a certain score. If your score is at the 70th percentile, you outperformed 70% of participants. The formula for percentile rank can vary, but a common approach is: (number of scores below x + 0.5 × number of scores equal to x) ÷ total scores × 100%. Percentiles are widely used in standardized tests, health metrics (like baby growth charts), or demographic analyses. Understanding your percentile context clarifies how a result stands relative to a larger population, aiding well-informed decisions and interpretations.
