A score of 0.60 standard deviation represents what score of percentile?
It depends on the underlying distribution. If Gaussian (standrad normal) then the percentile is 77.
What is the standard deviation of a standard normal distribution?
The standard deviation in a standard normal distribution is 1.
In the standard normal distribution the standard deviation is always what?
The standard deviation in a standard normal distribution is 1.
What is percentile deviation?
A standard deviation in statistics is the amount at which a large number of given values in a set might deviate from the average. A percentile deviation represents this deviation as a percentage of the range.
A score of -1 standard deviation represents what percentile rank approximately?
approximately 32nd percentile
A score of 0.60 standard deviation represents what score of percentile?

What is the standard deviation of a standard normal distribution?
The standard deviation in a standard normal distribution is 1.
How much is 84 percentile equals mean plus 1 standard deviation or mean plus 1.4 standard deviation. Can you give me reference also please?
The cumulative probability up to the mean plus 1 standard deviation for a Normal distribution - not any distribution - is 84%. The reference is any table (or on-line version) of z-scores for the standard normal distribution.
In the standard normal distribution the standard deviation is always what?
The standard deviation in a standard normal distribution is 1.
What is percentile deviation?
A standard deviation in statistics is the amount at which a large number of given values in a set might deviate from the average. A percentile deviation represents this deviation as a percentage of the range.
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.
A score of -1 standard deviation represents what percentile rank approximately?
approximately 32nd percentile
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
