Characteristics of the F-distribution
1. 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.

The F distribution can't be negative.
In general the distribution of F-ratio means what
No they are not the same.
I apologize my question should have read what are the characteristics of a standard normal probability distribution? Thank you
Skewness is not a characteristic.
