How is percentile calculated?
Calculating percentile
- Put your data in ascending order. When calculating the percentile of a set of data, such as test scores, arrange the values in ascending order, starting with the lowest value and ending with the highest.
- Divide the number of values below by the total number of values.
- Multiply the result.
How do you calculate percentile score?
Percentiles are frequently useful to understand the test scores and biometric measurements in our day-to-day routine.
- Percentile is calculated by the ratio of the number of values below ‘x’ to the total number of values.
- Formula for Percentile.
- Percentile (P) = (Number of Values Below “x” / Total Number of Values) × 100.
How do I calculate the percentile?
Hence, the percentile formula is:
- Percentile = (n/N) × 100.
- Percentile = (Number of Values Below “x” / Total Number of Values) × 100.
- Example 1: The scores obtained by 10 students are 38, 47, 49, 58, 60, 65, 70, 79, 80, 92.
