What is the standard deviation of a standard normal distribution?
The standard deviation in a standard normal distribution is 1.
How do you use the z-score to determine a normal curve?
If the Z-Score corresponds to the standard deviation, then the distribution is "normal", or Gaussian.
In the standard normal distribution the standard deviation is always what?
The standard deviation in a standard normal distribution is 1.
The mode and standard deviation of a distribution are 55 and 4.33 respectively?
The statement is probably: The mean and standard deviation of a distribution are 55 and 4.33 respectively.
What is the standard deviation of the mean of 9.65?
It depends on what the distribution is. In a Normal or Gaussian distribution, the standard deviation is the square root of the mean, so it could be 3.1 but, again, it depends on the distribution.
What is the standard deviation of a standard normal distribution?
The standard deviation in a standard normal distribution is 1.
How do you use the z-score to determine a normal curve?
If the Z-Score corresponds to the standard deviation, then the distribution is "normal", or Gaussian.
In the standard normal distribution the standard deviation is always what?
The standard deviation in a standard normal distribution is 1.
Why does a Uniform distribution have a greater standard deviation?
The answer depends on greater standard deviation that WHAT!
A standard normal distribution has a mean of and standard deviation of?
Mean 0, standard deviation 1.
What does standard deviation tell about distribution and varity?
It is a measure of the spread of the distribution. The greater the standard deviation the more variety there is in the observations.
What does standard deviation describes?
Standard deviation describes the spread of a distribution around its mean.
The standard deviation of the distribution of means is also known as the population standard deviation?
Yes.
The national average SAT score is 1028 with a standard deviation of 92 Assuming a normal distribution what score corresponds to the 90th percentile?
124
When the population standard deviation is not known the sampling distribution is a?
If the samples are drawn frm a normal population, when the population standard deviation is unknown and estimated by the sample standard deviation, the sampling distribution of the sample means follow a t-distribution.
The mode and standard deviation of a distribution are 55 and 4.33 respectively?
The statement is probably: The mean and standard deviation of a distribution are 55 and 4.33 respectively.
The mean of the distribution is 2.89 with a standard?
The mean of a distribution gives no information about the standard deviation.
