1. What is Percentile?

Percentile is a measure that indicates the value below which a given percentage of observations in a group of observations fall. For example, if a student is in the 90th percentile, they scored better than 90% of the group.

2. How Does the Calculator Work?

The calculator uses the percentile formula:

Where:

• \( Rank \) — The student's rank in the class
• \( Students \) — Total number of students in the class

Explanation: The formula calculates what percentage of students scored below the given rank.

3. Importance of Percentile Calculation

Details: Percentiles are crucial for comparing a student's performance against their peers, determining relative standing in competitive exams, and assessing academic progress.

4. Using the Calculator

Tips: Enter the student's rank (must be between 1 and total students) and the total number of students. Both values must be positive integers.
