# PERCENTILE

The PERCENTILE function calculates the k-th percentile of a set of values. It is commonly used in data analysis and statistics to determine a specific value below which a certain percentage of data falls.

## Syntax ๐

=PERCENTILE(`array`

, `k`

)

`array` | Array or range of values for which you want to find the k-th percentile. |

`k` | The percentile to calculate (0 โค k โค 1). |

## About PERCENTILE ๐

When you're exploring data sets and seeking insights on the distribution of values, turn to the PERCENTILE function in Excel. This versatile tool allows you to pinpoint specific percentiles within your data, aiding in the analysis of datasets across various disciplines, such as business, finance, and research. By leveraging the k-th percentile, you can obtain valuable information on the spread and characteristics of your data, enabling informed decision-making and comprehensive statistical assessments.

## Examples ๐

Suppose you have a list of test scores in cells A1 to A10 and you want to find the 75th percentile of the scores. The PERCENTILE formula would be: =PERCENTILE(A1:A10, 0.75). This will return the value that represents the 75th percentile of the test scores.

Consider a dataset of sales figures in cells B1 to B20. If you wish to determine the 90th percentile sales value, you would utilize the PERCENTILE function as follows: =PERCENTILE(B1:B20, 0.9). This calculation will yield the sales figure below which 90% of the data falls.

## Notes ๐

The PERCENTILE function requires a numeric array or range as the first argument. The second argument 'k' represents the desired percentile as a decimal between 0 and 1. Ensure to adjust the 'k' value accordingly to obtain the respective percentile value of the dataset.

## Questions ๐

**How does the PERCENTILE function determine the k-th percentile?**

The PERCENTILE function calculates the k-th percentile by sorting the data values in ascending order and then finding the value that corresponds to the specific percentile. It provides a precise measure of where a certain percentage of data points fall within the dataset.

**What does the 'k' value represent in the PERCENTILE function?**

The 'k' value in the PERCENTILE function represents the desired percentile to calculate. It is a decimal number between 0 and 1, indicating the percentage of data points that are below the obtained percentile value.

**Can the PERCENTILE function be used on non-numeric values?**

No, the PERCENTILE function requires a numeric array or range of values as input. It is designed to calculate percentiles on numerical datasets and cannot be applied to non-numeric data.
