Guide to using the PERCENTILE function in Excel - Illustrated Examples

Using the PERCENTILE function in Excel helps you calculate quickly, providing accurate results. But do you know how to use this function yet? If not, refer to the syntax and example of the PERCENTILE function below.

The PERCENTILE function returns the k-th percentile result of values in the dataset or data range. The percentile value you want to determine must always be between 0 and 1, including 0 and 1. Otherwise, the function will fail to compute and return an error message.

Syntax: PERCENTILE(array,k)

Where:

- array: Mandatory - Represents the dataset or data range.
- k : Mandatory - Represents the percentile value within the range 0..1, inclusive.

Consider an example

Given an Excel spreadsheet with actual values corresponding to the parameters of the PERCENTILE function. In this example, we compute with a dataset consisting of 5 values: 5, 3, 2, 4, 1 and a percentile value of 0.8 (note that this percentile value must be within the range 0..1, inclusive):

Enter the formula into cell C8. The calculated result of the function is 4.2:

So now you know how to use the PERCENTILE function in Excel. Even if you input the value of k not according to the standard, the PERCENTILE function still employs an interpolation mechanism to determine the percentile value for you. This is also a very useful feature of this calculation function.

Frequently Asked Questions

What is the purpose of using the PERCENTILE function in Excel?

The PERCENTILE function in Excel is used to quickly calculate the k-th percentile of a dataset. This function provides accurate results, helping users understand the distribution of values within their data range.

How do I properly use the PERCENTILE function in Excel?

To use the PERCENTILE function, input the syntax as follows: PERCENTILE(array, k). Ensure that the 'array' is your dataset and 'k' is the percentile value between 0 and 1, inclusive.

What happens if the k value is outside the range of 0 to 1?

If the k value is outside the range of 0 to 1, the PERCENTILE function will return an error message. It's crucial to ensure that k falls within this inclusive range to avoid computation errors.

Can the PERCENTILE function handle incorrect k values automatically?

Yes, the PERCENTILE function can handle incorrect k values by employing an interpolation mechanism. This feature allows it to estimate the percentile value even when the input is not standard.
