The Excel PERCENTILE.INC function returns the k'th percentile (i.e. the value below which k% of the data values fall) for a supplied range of values and a supplied k (between 0 & 1 inclusive).
The function is new in Excel 2010 and so is not available in earlier versions of Excel. However, Percentile.Inc is simply a renamed version of the old Percentile function, which is available in earlier versions of Excel.
The syntax of the Percentile.Inc function is:
Where the function arguments are:
|array||-||The array of data values for which you want to calculate the k'th percentile.|
|k||-||The value, between 0 and 1 (inclusive), of the required percentile.|
If k is not a multiple of 1/(n-1), (where n is the number of values in the supplied array), the Percentile.Inc function interpolates between the values in the supplied array, to calculate the percentile value.
Column B of the spreadsheet below shows four examples of the Excel Percentile.Inc function, used to calculate the k'th percentile of the set of values in cells A1-A6. In each case, a different value of k is specified.
Note that in the above examples:
Further examples of the Excel Percentile.Inc function are provided on the Microsoft Office website
If you get an error from the Excel Percentile.Inc function this is likely to be one of the following:
|#VALUE!||-||Occurs if the supplied value of k is non-numeric.|
