Percentile vs. Ventile — What's the Difference?
Edited by Tayyaba Rehman — By Urooj Arif — Updated on May 17, 2024
Percentile ranks data within a distribution, showing the percentage below a specific value, while ventile divides data into 20 equal parts for more detailed analysis.

Key Differences
Percentile measures how a value compares to the rest of a dataset by indicating the percentage of data points below it. For instance, the 70th percentile means a value is higher than 70% of the data. Ventile, on the other hand, divides data into 20 equal parts, each representing 5% of the dataset, providing a more granular view of distribution.
Percentile is commonly used in standardized testing to show student performance relative to peers. For example, scoring in the 90th percentile means a student scored better than 90% of the test-takers. Whereas ventile might be used in more detailed statistical analysis, splitting data into 20 groups to better understand variations within smaller segments.
When comparing the utility, percentiles are often more intuitive for general understanding, giving a quick grasp of where a value stands. Ventiles, while less commonly used, are valuable in economic and medical research for their finer division, allowing more precise data analysis.
In terms of application, percentiles are widely used in educational assessments, health indicators, and economic benchmarks. Ventiles, although less widespread, are particularly useful in detailed academic research, providing a more nuanced understanding of data distributions.
Percentiles can simplify interpretation by converting data into a scale from 1 to 100, making it easier to understand for non-specialists. Ventiles, splitting data into 20 parts, require a bit more explanation but offer greater detail for those needing in-depth analysis.

Percentile
In statistics, a percentile (or a centile) is a score below which a given percentage of scores in its frequency distribution falls (exclusive definition) or a score at or below which a given percentage falls (inclusive definition). For example, the 50th percentile (the median) is the score below which (exclusive) or at or below which (inclusive) 50% of the scores in the distribution may be found.
Ventile
Ventile, is a registered trademark used to brand a special high-quality woven cotton fabric first developed by scientists at the Shirley Institute in Manchester, England. Originally created to overcome a shortage of flax used for fire hoses and water buckets, its properties were also found to be ideal for pilots' immersion suits.Extra-long-staple (ELS) cotton fibres are used to form a low-twist yarn, which is then woven into a tight high-density textile to create a 100% cotton fabric, capable of providing an effective barrier against inclement weather.
Percentile
