Excel FDIST Function

Description

The Excel FDIST function returns the (right-tailed) F probability distribution which is usually used to measure the degree of diversity between two data sets.

Note: This function has been replaced with one or more new functions that may provide improved accuracy after Excel 2010 version. This function is still can be available but considering it may be not available in the future, you should better study to use the new function from now.

Syntax and arguments

Arguments

Remarks

1. The function returns #VALUE! error value if any arguments of FDIST function is a non-numeric value.

2. The function returns #NUM! error value when:

• X is negative;
• Deg_freedom1 is <1 or ≥10 ^ 10;
• Deg_freedom2 is <1 or ≥10 ^ 10;

3. If deg_freedom1 or deg_freedom2 is not an integer, it will be truncated.

4. FDIST function is calculated as FDIST=P( F>x ), where F is a random variable that has an F distribution with deg_freedom1 and deg_freedom2 degrees of freedom.

Version

Excel 2007

Usage and Examples

Basic usage

For instance, in list C2:C4 contains arguments x, deg_freedom1, and deg_freedom2, to get the relative F probability distribution, please use the formula as these:

=FDIST(C2,C3,C4)

Press Enter key.
