PERCENTILE.INC
The PERCENTILE.INC function returns the kth percentile of values in a range, with k being a value between 0 and 1. This function includes the endpoints of the range in the calculation. It is useful for statistical analysis.
Syntax 🔗
=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 🔗
Use the PERCENTILE.INC function in Excel to find a specific percentile in your dataset. This function calculates the kth percentile value for a given array or range, where k is the desired percentile on a scale from 0 (0%) to 1 (100%). This is helpful in statistical analysis and business scenarios where you need precise percentile calculations to assess data distribution and performance metrics.
To use PERCENTILE.INC, input the array or range of values and specify the desired percentile value (k). The function returns the value at the specified percentile, indicating the threshold below which a certain percentage of data points fall.
PERCENTILE.INC differs from the older PERCENTILE function by using a method that interpolates between data points, aligning with current statistical practices and providing more accurate results. This function helps you extract key insights from datasets by identifying specific percentiles accurately.
Examples 🔗
To find the 60th percentile of exam scores located in cells A1:A10, use the following formula:
=PERCENTILE.INC(A1:A10, 0.6)
This formula calculates the score at the 60th percentile of your dataset.
For sales data in cells B1:B20, to determine the 75th percentile, apply this formula:
=PERCENTILE.INC(B1:B20, 0.75)
This will return the value at the 75th percentile of the sales data.
Notes 🔗
Ensure 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 for a given dataset.
Questions 🔗
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.
