How to Calculate Percentiles Algebra Study.com

WebThe first step is to compute the rank (R) of the 25th percentile. This is done using the following formula: R = P/100 x (N + 1) where P is the desired percentile (25 in this case) and N is the number of numbers (8 in this case). Therefore, R = 25/100 x (8 + 1) = 9/4 = 2.25. If R is an integer, the Pth percentile is the number with rank R.
