- Use the units shown beside each field.
- Results update automatically whenever you change an input.
- Displayed values use up to four decimal places, or scientific notation for very small or large numbers. Calculations use standard floating-point arithmetic; exact integer and fraction tools identify their own precision rules.
- Percentile ranks depend on the tie convention; they are not the same operation as estimating a percentile value.
Example Calculation
Example inputs
- Data: 1, 2, 2, 4
- Target value: 2
- Tie convention: Midrank: below + half equal
In1,2,2,4 the midrank percentile of2 is(1+½×2)/4=50%.
Frequently asked questions
How do I use this calculator?
Enter data, target value, tie convention. The result updates automatically. Use Reset to restore the example values.
What method does it use?
rank percentage=100 × selected cumulative count / n. Percentile ranks depend on the tie convention; they are not the same operation as estimating a percentile value.
Why might a rounded result differ?
The calculation keeps full numeric precision internally, then rounds the displayed result. Rounding intermediate steps by hand can produce a slightly different answer.
Are my inputs saved online?
No. This calculator processes your inputs in your browser. A recently used list stores only calculator names on this device, not your entered values.
