normal distribution  A theoretical frequency distribution of a dataset in which the distribution of values can be graphically represented as a symmetrical bell curve Normal The standard normal distribution is a special normal distribution with a µ = 0 and σ = 1 We can use the Z-score to standardize any normal random variable,

Basic Properties of the Standard Normal Curve¶ · The total area under the standard normal curve is 1 · The A normal distribution is completely determined by its mean μ μ and its standard deviation σ σ , which means there are an infinite number of normal distributions

How to Use the Normal Distribution · 68% of the data is within +- 1 standard deviation of the average · 95% of the data is within +- 2 standard deviations of The normal distribution , also referred as bell curve, is very useful due to the central limit theorem Normal distribution states
