State the mean and standard deviation of the standard normal distribution; Use a Z table; Use the normal calculator; Transform raw data to Z scores. As discussed in the introductory section, normal distributions do not necessarily have the same means and standard deviations. read more

For any positive integer n, any normal distribution with mean μ and variance σ 2 is the distribution of the sum of n independent normal deviates, each with mean μ/n and variance σ 2 /n. This property is called infinite divisibility. read more

A normal distribution with a mean of 0 and a standard deviation of 1 is called a standard normal distribution. Areas of the normal distribution are often represented by tables of the standard normal distribution. read more

But there are many cases where the data tends to be around a central value with no bias left or right, and it gets close to a "Normal Distribution" like this: A Normal Distribution The "Bell Curve" is a Normal Distribution. read more
