Is the a normal distribution curve negative or positive?
Neither. It is symmetrical.
Does mode equals the median normal distribution?
Yes it is. The normal distribution is symmetrical around the mode. Therefore the median has to be the same :)
Is symmetrical a characteristic of a normal distribution?
The Normal ditribution is symmetric but so are other distributions.
Define a normal random variable?
I have included two links. A normal random variable is a random variable whose associated probability distribution is the normal probability distribution. By definition, a random variable has to have an associated distribution. The normal distribution (probability density function) is defined by a mathematical formula with a mean and standard deviation as parameters. The normal distribution is ofter called a bell-shaped curve, because of its symmetrical shape. It is not the only symmetrical distribution. The two links should provide more information beyond this simple definition.
What is the difference between beta and normal distribution?
The probability density functions are different in shape and the domain. The domain of the beta distribution is from 0 to 1, while the normal goes from negative infinite to positive infinity. The shape of the normal is always a symmetrical, bell shape with inflection points on either sides of the mean. The beta distribution can be a variety of shapes, symmetrical half circle, inverted (cup up) half circle, or asymmetrical shapes. Normal distribution has many applications in classical hypothesis testing. Beta has many applications in Bayesian analysis. The uniform distribution is considered a specialized case of the beta distribution. See related links.
How the symmetric distribution is always normal?
The statement is false. The binomial distribution (discrete) or uniform distribution (discrete or continuous) are symmetrical but they are not normal. There are others.
Are all symmetric distribution are normal?
No. The binomial distribution (discrete) or uniform distribution (discrete or continuous) are symmetrical but they are not normal. There are others.
In a perfectly symmetrical bell-shaped normal distribution?
Normal distribution is a perfectly symmetrical bell-shaped normal distribution. The bell curve is used to find the median, mean and mode of a function.
What is symmetrical normal distribution?
The Normal distribution is, by definition, symmetric. There is no other kind of Normal distribution, so the adjective is not used.
What is true regarding the normal distribution?
It is symmetrical
Can a distribution be symmetrical and non-normal?
Certainly.
Does all symmetrical distributions are normal distribution?
It is not necessary that all symetric distribution may be normal.
Is the a normal distribution curve negative or positive?
Neither. It is symmetrical.
Does mode equals the median normal distribution?
Yes it is. The normal distribution is symmetrical around the mode. Therefore the median has to be the same :)
Is symmetrical a characteristic of a normal distribution?
The Normal ditribution is symmetric but so are other distributions.
The bell curve is a normal distribution. It's a distribution. 1.false 2.symmetrical 3.lopsided 4.accurate?
symmetrical :)i do believe!hope this helps!Pixiex
Is it true that the curve for the normal distribution is symmetrical in respect to the mean?
yes it is true
