This F Test calculator can help you calculate the F value for a statistical test consisting of two set of values, that follows the F-distribution under the null hypothesis.
How does this F-Test calculator work?
This statistical F-Test calculator can assist you when trying to determine the F value and the sample variance for two given data sets by applying these formulas:
F Value = s12/ s22
n = count of the values within the data set
xi … xn = numbers in the sample
x bar = sample mean
s2= sample variance
s12 = sample variance for first set of data
s22 = sample variance for first set of data
Please note that the numbers should be placed one per line within the two boxes.
Example of a calculation
Assuming we have the following two data sets let’s calculate the F value:
|First set||Second set|
The results in this case are:
■ F Value = 0.102089
■ Sample variance for first data set (s12) = 58.166667
■ Sample variance for second data set (s22) = 569.76666707 Jul, 2015 | 0 comments
