The Excel PERCENTILE.EXC function returns the k'th percentile of a supplied range of values for a given value of k, within the range 0 to 1 (exclusive).
The function is new in Excel 2010 and so is not available in earlier versions of Excel.
The format of the Percentile.Exc function is :
PERCENTILE.EXC( array, k )
Where the function arguments are:
If k is not a multiple of 1/(n+1), (where n is the number of values in the supplied array), the function interpolates between the values in the supplied array, to calculate the percentile value. However, if k is < 1/(n+1) or k is > n/(n+1), the function is unable to interpolate, and so returns an error.
Percentile.Exc Function Examples
The spreadsheets below show examples of the Excel Percentile.Exc function used to calculate the k'th percentile of a set of values in cells A1 - A4 of the sample spreadsheet, for different values of k.
The formulas for the functions are shown in the spreadsheet on the left, and the results are shown in the spreadsheet on the right.
