Percentile vs. Percentage: What's the Difference?

Edited by Huma Saeed || By Sumera Saeed || Updated on October 20, 2023
A percentile indicates a relative rank within a set, while a percentage represents a proportion out of 100.

Key Differences

A percentile refers to a measure that tells us what proportion of a given dataset falls below a particular value. For instance, if a student scores in the 90th percentile on a test, they've scored higher than 90% of the other students. On the other hand, a percentage is a mathematical representation of a ratio as a fraction of 100. It tells you the part of a whole.

When considering a dataset, the percentile gives a comparative standing. If someone is in the 75th percentile for height, it means they are taller than 75% of their peers. Percentage, in contrast, would denote the actual fraction of a particular subset. For example, if 15% of people in a room wear glasses, that's a direct proportion, not a ranking.

Percentile is commonly used in standardized testing or any situation where you want to compare an individual's performance against others. It offers context about relative standing. Percentage is more ubiquitous, used in various contexts, from finance to science, indicating parts of a whole.

In the context of growth charts, a child's weight might be in the 80th percentile, meaning they weigh more than 80% of children their age. However, if we say 60% of children in a school are vaccinated, we're using percentage to convey a proportion of the total number of children.

To sum it up, while both percentile and percentage quantify data, they serve different purposes. Percentile ranks data points in a set, while percentage communicates a portion out of a total 100.
