How to Calculate Percentile
Complete 4-Step Mathematical Methodology with Worked Step-by-Step Practical Example
Sort the Data
Arrange the data points in ascending order (from smallest to largest). Let the sorted dataset be represented as:
Where n is the total number of data points in the dataset.
Calculate Percentile Rank
Find the rank position r for the desired percentile p using the formula:
• p is the desired percentile (e.g., 90 for 90th percentile).
• n is the total number of items.
Extract or Interpolate Value
Split the calculated rank r into its integer component (ri = ⌊r⌋) and fractional component (rf = r - ri):
4. Practical Step-by-Step Example
The ordered dataset (n = 5) is:
Substitute p = 70 and n = 5 into formula:
Deconstruct rank r = 3.8:
Integer (ri) = 3 | Fraction (rf) = 0.8
Locate x3 = 30 & x4 = 40
