Percentile Rank, Decile, Ordinal Rank Calculator

Percentile and Ordinal Rank Calculator
An online percentile calculator with ordinal rank.
Percentile Rank Formula
Rank = (P / 100) * N
Where,
P is Percentile,
N is Number of items
Decile Formula

Where,
L is lower boundary
F is cummulative frequency
f is frequency
N is total frequency
k = nth decile, where n = 1, 2, 3, 4, 5, 6, 7, 8, and 9

How to find percentile and ordinal rank ?
Example Question: Find out where the 25th percentile is in the below list.
Score | Rank |
---|---|
30 | 01 |
33 | 02 |
43 | 03 |
53 | 04 |
56 | 05 |
67 | 06 |
68 | 07 |
72 | 08 |
Step 1:Arrange the data in ascending order
30, 33, 43, 53, 56, 67, 68, 72
Step 2:Calculate what rank is at the 25th percentile by using the following formula
Rank = P / 100 * (N)
Where P is Percentile = 25, N is Number of items = 8
Rank = 25 / 100 * (8) = 0.25 * 8 = 2.
The 25th percentile is the average of the values in the 1th and 2th positions (33 and 43 respectively).
The 25th percentile is (33 + 43) / 2 = 38
In this case, the 25th percentile score is 38, which makes more sense as its in the middle of 43 and 33.
