What is the difference between percentile and quantile?

Definitions

percentile

- Describing a statistical measure that divides a distribution into 100 equal parts.

- Referring to the position of a particular value in a distribution relative to the other values.

- Talking about a way to compare an individual's performance or score to a larger group.

quantile

- Describing a statistical measure that divides a distribution into equal parts.

- Referring to the position of a particular value in a distribution relative to the other values.

- Talking about a way to compare an individual's performance or score to a larger group.

List of Similarities

• 1. Both percentile and quantile are statistical measures used to divide a distribution into parts.
• 2. Both percentile and quantile refer to the position of a particular value in a distribution relative to the other values.
• 3. Both percentile and quantile can be used to compare an individual's performance or score to a larger group.

What is the difference?

• 1. Definition: Percentile divides a distribution into 100 equal parts, while quantile divides a distribution into any number of equal parts.
• 2. Number of parts: Percentile always divides a distribution into 100 parts, while quantile can divide a distribution into any number of parts.
• 3. Naming convention: Percentile is named based on the percentage of values below a particular value, while quantile is named based on the fraction of values below a particular value.
• 4. Calculation: Percentile is calculated by ranking the values in a distribution and determining the percentage of values below a particular value, while quantile is calculated by dividing the distribution into equal parts and determining the fraction of values below a particular value.
• 5. Usage: Percentile is more commonly used than quantile in everyday language and is often used in educational and psychological contexts, while quantile is more commonly used in statistical and mathematical contexts.

📌

Remember this!

Percentile and quantile are both statistical measures used to divide a distribution into parts and compare an individual's performance or score to a larger group. However, percentile always divides a distribution into 100 equal parts, while quantile can divide a distribution into any number of equal parts. Additionally, percentile is more commonly used in everyday language, while quantile is more commonly used in statistical and mathematical contexts.
