It is a consequence of the Central Limit Theorem (CLT).
Suppose you have a large number of independent random variables. Then, provided some fairly simple conditions are met, the CLT states that their mean has a distribution which approximates the Normal distribution - the bell curve.

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.
Why you prefer normal distribution over other distributions in statistics?
we prefer normal distribution over other distribution in statistics because most of the data around us is continuous. So, for continuous data normal distribution is used.
What are the advantages of using standard normal distribution over the normal distribution?
The standard normal distribution is tabulated. The critical values for various outcomes can therefore be worked out easily from tables. The normal distribution is extremely difficult to integrate: most people, even with a university degree in mathematics will be unable to do so. So working out the probability of events from the normal distribution is near enough impossible.
What is the perfect standard normal distribution?
The standard normal distribution is a subset of a normal distribution. It has the properties of mean equal to zero and a standard deviation equal to one. There is only one standard normal distribution and no others so it could be considered the "perfect" one.
What does probalility distribution mean?
In parametric statistical analysis we always have some probability distributions such as Normal, Binomial, Poisson uniform etc.In statistics we always work with data. So Probability distribution means "from which distribution the data are?
What are the characteristics of populations?
There are so many characteristics of human population. Some of the common features of the human population include densities, ethnicities, distribution and languages among others.
Does the t distribution becomes more skewed As the degree of freedom increases?
The t-distribution is symmetric so the question is irrelevant.The t-distribution is symmetric so the question is irrelevant.The t-distribution is symmetric so the question is irrelevant.The t-distribution is symmetric so the question is irrelevant.
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 are common methods for gaining support for Linux?
The main common support for whichever Linux Distribution is being used, is the internet: websites, blogs, forums, screencasts on youtube, user groups, ebooks and printed books, and so on.
How do communities use nuclear energy?
Nuclear produced electricity just goes into the common grid distribution system, so no community relies on nuclear energy alone.
A famine happens when a large percentage of the population is so undernourished that death by starvation is common. Famine is most commonly caused by poor food distribution and?
Sudden climate change
Can you send me to a geographical distribution diagram of the Gobi Desert?
this is a geographical distribution of gobi desert i think so
Why does nature matter to the world?
Because the world without nature would be void of life. So no nature no life. So protect nature, don't contaminate.
Does stantler have the nature frisk?
there is no nature of that kind. so no, it can not.
Why was Leonardo da Vinci so fascinated by nature?
Leonardo was so fascinated by nature because he thought that nature was the beautiful thing
The F-distribution is symetrical around mean zero True or False?
The F-distribution is either zero or positive, so there are no negative values for F. This feature of the F-distribution is similar to the chi-square distribution. The F-distribution is skewed to the right. Thus this probability distribution is nonsymmetrical.
Why in a normal distribution the distribution will be less spread out when the standard diviation of the raw scores is small?
The standard deviation (SD) is a measure of spread so small sd = small spread. So the above is true for any distribution, not just the Normal.
