What else can I help you with?
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 a normal distribution always symmetrical?
yes, it's always symmetric
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.
Does symmetrical distribution have multiple peaks?
It can have multiple peaks, but most symmetrical distributions do not.
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.
Can a distribution be symmetrical and non-normal?
Certainly.
What is true regarding the normal distribution?
It is symmetrical
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.
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.
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 :)
What is the characteristic of a normal distribution?
The Normal (or Gaussian) distribution is a symmetrical probability function whose shape is determined by two values: the mean and variance (or standard deviation).According to the law of large numbers, if you take repeated independent samples from any distribution, the means of those samples are distributed approximately normally. The greater the size of each sample, or the greater the number of samples, the more closely the results will match the normal distribution. This characteristic makes the Normal distribution central to statistical theory.
Is not a characteristics of a normal distribution.?
Skewness is not a characteristic.
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
