Returns F probability distribution. Use this function to determine if there is a difference in the degree of variation between two data series.
For example, analyze the test scores of boys and girls entering college to determine whether girls’ scores change to a different degree than boys’.
grammar
FDIST(x,degrees_freedom1,degrees_freedom2)
X is the value used to perform the function calculation.
Degrees_freedom1 The degree of freedom of a molecule.
Degrees_freedom2 Degree of freedom in the denominator.
Instructions
■ If any of the arguments is non-numeric, FDIST returns the #VALUE! Error value. .
■ FDIST returns the #NUM! Error value if any of the following occurs: .
- x is negative
degrees_freedom1 < 1 or degrees_freedom1 ≥ 10^10
degrees_freedom2< 1 or degrees_freedom2 ≥ 10^10
■ If degrees_freedom1 or degrees_freedom2 is not an integer, it is rounded by truncation.
■ The formula for calculating function FDIST is FDIST=P(F> x).
Where F is a random variable with F distribution and degrees_freedom1 and degrees_freedom2 degrees of freedom.
I want to create a clean, concise and efficient office reference manual, in order to maintain a good reference experience, I did not add any third-party advertisements in my blog, of course, if you are willing, you can watch the following video, it can bring me some income, so that I can better maintain the server to provide higher quality service, thank you for your help and support.
