# PERCENTILE.INC

The PERCENTILE.INC function returns the kth percentile of values in a range, where k is a value between 0 and 1, inclusive.

## Syntax ðŸ”—

=PERCENTILE.INC(`array`

, `k`

)

`array` | The array or range of values for which you want to find the kth percentile. |

`k` | The percentile value, a number between 0 and 1. |

`array` | The array or range of values from which you want to calculate the kth percentile. |

`k` | A value between 0 and 1 that represents the percentile you want to find. |

## About PERCENTILE.INC ðŸ”—

When you need to determine a specific percentile within a dataset, PERCENTILE.INC in Excel comes to the rescue. This function efficiently calculates the kth percentile value for a given array or range, where k represents the desired percentile on a scale from 0 (0%) to 1 (100%). It proves particularly useful in statistical analysis and business scenarios requiring precise percentile calculations to evaluate data distribution and performance metrics effectively.

To leverage PERCENTILE.INC effectively, input the array or range of values from which you want to derive the percentile, along with the desired percentile value (k). The function then returns the value at the specified percentile, which signifies the threshold below which a certain percentage of data points fall.

Notably, PERCENTILE.INC differs from the older PERCENTILE function in terms of calculation method. PERCENTILE.INC aligns with modern statistical practices by interpolating between data points to determine percentile values, providing more accurate results compared to its predecessor.

In essence, PERCENTILE.INC acts as your statistical ally in Excel, aiding you in extracting key insights from datasets by pinpointing specific percentiles with precision and reliability.

## Examples ðŸ”—

Given a dataset of exam scores in cells A1:A10, where you wish to find the 60th percentile, you would use the formula:

=PERCENTILE.INC(A1:A10, 0.6)

This formula will return the score that corresponds to the 60th percentile in the dataset.

If you have sales data in cells B1:B20 and wish to calculate the 75th percentile of these values, the formula would be:

=PERCENTILE.INC(B1:B20, 0.75)

This will provide you with the value at the 75th percentile of the sales dataset.

## Notes ðŸ”—

Ensure that the array provided to the PERCENTILE.INC function contains numeric values. Percentile values can range from 0 to 1, inclusive, representing the desired percentage point. The function interpolates between data points to compute percentile values accurately for a given dataset.

## Questions ðŸ”—

**How is the percentile calculated by the PERCENTILE.INC function?**

The PERCENTILE.INC function calculates the percentile by sorting the dataset in ascending order, determining the position that corresponds to the desired percentile (k) within the sorted array, and interpolating between data points if necessary to derive the precise percentile value.

**What is the main difference between PERCENTILE.INC and the older PERCENTILE function?**

The key distinction lies in the calculation method. PERCENTILE.INC uses an inclusive interpolation method to compute percentile values accurately, especially for datasets with limited data points, whereas the older PERCENTILE function did not interpolate between data points, potentially leading to less precise results.

**Can I use the PERCENTILE.INC function with non-numeric values in the array?**

No, the PERCENTILE.INC function requires the array or range of values to contain numeric data only. Ensure that the dataset provided to the function consists of numerical values for accurate percentile calculations.
