A quick answer: F is the ratio of two Chi squared divided by their degrees of freedom respectively.
F = ((X1)2/v1) / ((X2)2/v2).
Where:
(X1)2 & (X2)2 are the Chi squared for the variables 1...
The F distribution is used to test whether two population variances are the same. The sampled populations must follow the normal distribution. Therefore, as the sample size increases, the F...
