When studying the behaviour of the sum of independent, identically distributed (iid) Gaussian (normal) variables. The F-distribution is used mainly in the analysis of variance where the errors - between the observed value and those predicted by a model - are assumed to be iid Normal.

When we use f distribution?

When comparing the sums of squares of normal variates.

Can the F distribution be negative?

The F distribution can't be negative.

The F-distribution is symetrical around mean zero True or False?

The F-distribution is either zero or positive, so there are no negative values for F. This feature of the F-distribution is similar to the chi-square distribution. The F-distribution is skewed to the right. Thus this probability distribution is nonsymmetrical.

Is the f distribution negatively skewed?

In general the distribution of F-ratio means what

Is the f distribution a continuous distribution?


Is f distribution a discrete distribution?

No, it is continuous.

What distribution does the F distribution approach as the sample size increases?

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 distribution approaches the normal distribution.

Is the F distribution same as t distribution?

No they are not the same.

Is the F distribution a symmetric distribution?

No.It is asymmetric.

How do you explain the characteristics of the F Distribution?

Characteristics of the F-distribution1. It is not symmetric. The F-distribution is skewed right. That is, it is positively skewed.2. The shape of the F-distribution depends upon the degrees of freedom in the numerator and denominator. This is similar to the distribution and Student's t-distribution, whose shape depends upon their degrees of freedom.3. The total area under the curve is 1.4. The values of F are always greater than or equal to zero. That is F distribution can not be negative.5. It is asymptotic. As the value of X increases, the F curve approaches the X axis but never touches it. This is similar to the behavior of normal probability distribution.

What is exponential distribution?

The exponential distribution is a continuous probability distribution with probability density definded by: f(x) = ke-kx for x ≥ 0 and f(x) = 0 otherwise.
