The following article introduces you to the F.DIST.RT function - one of the functions in the statistical function group is very popular in Excel.
Description: The function returns the right probability distribution F for 2 data sets. Support function from Excel 2010 version.
Syntax: F.DIST (x, deg_freedom1, deg_freedom2)
Inside:
- x: The value of the function, is a required parameter.
- deg_freedom1: The degree of freedom in the numerator, is a required parameter.
- deg_freedom2: The degrees of freedom in the denominator, are required parameters.
Attention:
- If any parameters are not numeric -> the function returns the #VALUE! Error value .
- If x <0 -> the function returns the #NUM! Error value
- If deg_freedom1 , deg_freedom2 are not whole numbers -> they are truncated to integers.
- If deg_freedom1 <1 or deg_freedom2 <1 -> the function returns the #NUM! Error value
- The F.DIST.RT function is calculated as F.DIST.RT = P (F> x) where F is a random variable.
For example:
Calculate the right probability distribution F according to the data in the following data table:
- In the cell to calculate enter the formula : = F.DIST.RT (D6, D7, D8)
- Press Enter -> probability of distribution F is:
- Where the function value is less than 0 -> the function returns the #NUM! Error value
- If the number of degrees of freedom in the numerator and sample is less than 1 -> the function returns the #NUM! Error value
Above are instructions and some specific examples when using F.DIST.RT function in Excel.
Good luck!
