The F.DIST.RT function returns the (righttailed) F Probability Distribution, which measures the degree of diversity between two data sets.
 This function was introduced in Excel 2010 and so is not available in earlier versions.
 The F.DIST.RT function replaces the FDIST function included in earlier versions of Excel.
Syntax
=F.DIST.RT(x,deg_freedom1,deg_freedom2)
Arguments
Argument  Description 

x  The numeric value at which the function is to be evaluated – must be positive 
deg_freedom1  An integer specifying the numerator degrees of freedom 
deg_freedom2  An integer specifying the denominator degrees of freedom 
Examples
A  B  C  D  

1  Data  Description  
2  18.3589  Value at which to evaluate the function  
3  8  Numerator degrees of freedom  
4  4  Denominator degrees of freedom  
5  
6  Formula  Result  Notes  
7  =F.DIST.RT(A2,A3,A4)  0.006663  F probability distribution for the supplied terms 
Usage note: Use this function to determine whether two data sets have different degrees of diversity. For example, you can examine the test scores of men and women entering college and determine if the variability in the females is different from that found in the males.
