How to calculate percentile rank
- Find the percentile of your data set. Calculate the percentile of the data set you’re measuring so you can calculate the percentile rank.
- Find the number of items in the data set.
- Multiply the sum of the number of items and one by 100.
- Divide the percentile by the product of 100 and n+1.
What is the 25th percentile of the data set?
The first quartile is referred to as Q1 or the lower quartile. This value is the 25th percentile, in which the lower quarter of the values fall below the 25th percentile while three quarters are above it. The second quartile, or Q2, is the value at the 50th percentile. This is the median of the data set.
What is the 25th 50th and 75th percentile?
Every score is in the 100th percentile. The 25th percentile is also known as the first quartile (Q1), the 50th percentile as the median or second quartile (Q2), and the 75th percentile as the third quartile (Q3). In general, percentiles and quartiles are specific types of quantiles.
What percentile is class rank?
Divide your class rank by the number of students in your grade, multiply by 100, then subtract that number from 100.

Is the 50th percentile the same as the 75th percentile?
Since half of the data is less than the median, and one-half is equal to 50%, we could call the median the 50th percentile. One-fourth is equal to 25%, and so the first quartile the 25th percentile. Similarly, the third quartile is the same as the 75th percentile.
Which is the 25th percentile of the data set?

When to interpolate in percentile.exc function?
If k is ≤ 0 or if k ≥ 1, PERCENTILE.EXC returns the #NUM! error value. If k is not a multiple of 1/ (n + 1), PERCENTILE.EXC interpolates to determine the value at the k-th percentile. PERCENTILE.EXC will interpolate when the value for the specified percentile lies between two values in the array.
