Function name:
PERCENTILE.INC

Category:
Statistical Analysis

Summary:
Calculates the alpha-percentile of data values in an array of numbers. Percentiles can be used to understand the significance of particular values within a data set. The nth percentile of a data set is the value below which n% of the data set lies. This function uses an alpha argument lying in the range 0 to 1 (inclusive), which corresponds to a percentage in the range 0% to 100%. For example, an alpha of 0.5 gives the 50th percentile, also known as the median.

Syntax:
PERCENTILE.INC(Data; Alpha)

Returns:
Returns a real number which is the scale value for the specified data set and alpha.

Arguments:
Data is an array or a reference to the range of cells that represents the array of data.

Alpha is a real number or a reference to the cell containing that number which represents the percentage of the scale between 0 and 1 (inclusive).


 * If Alpha is greater than 1 or less than 0 then the function returns an error value.
 * If Alpha is not a multiple of 1/(n-1) then the function interpolates to obtain the value between two data points, where n is the total number of data points. For example, if we have a data set with five values, then alpha values of 0, 0.25, 0.5, 0.75, and 1 will pick out the values in the data set in ascending order.

Additional details:

 * Alpha = 0.25 gives the first quartile, Alpha = 0.5 gives the median, and Alpha = 0.75 gives the third quartile.
