EXCEL F.DIST.RT FUNCTION

The F.DIST.RT function in Excel computes the (right-tailed) F Probability Distribution, which assesses the degree of diversity between two data sets.

Syntax :

=F.DIST.RT( xdeg_freedom1deg_freedom2 )

Parameters :

  • The function parameters are as follows:

x –

  • The (positive) numerical value at which the function should be evaluated.

deg freedom 1 –

  • An integer indicating the degrees of freedom in the numerator.

deg freedom2 –

  • An integer that specifies the degrees of freedom in the denominator.

Step By Step Guide of F.DIST.RT Function

Example :

The right – tailed F Probability Distribution is depicted in the chart below, with deg freedom1 (the numerator degrees of freedom) set to 1 and deg freedom2 (the denominator degrees of freedom) set to 2. If you wish to find the value of this function at x = 5, you may use the  Excel F.Dist.Rt function, as follows:

=F.DIST.RT( 5, 1, 2 )

This gives the probability 0.154845745.

  • #NUM! – This error occurs if either the specified value of x is 0 or the supplied deg freedom1 or deg freedom2 equals 1.
  • #VALUE! – This error occurs if any of the supplied parameters is not a number.
