A standard normal distribution has the following properties: Mean value is equal to 0; Standard deviation is equal to 1; Total area under the curve is equal to 1; and; Every value of variable x is converted into the corresponding z-score. You can check this tool by using the standard normal distribution calculator as well. If you input the mean ...

About this calculator. The normal distribution graph is also known as the bell curve. It is characterized by two parameters. The first one is the mean of a distribution; the graph is always symmetric about the mean, which means that half of the observations are greater than mean and half are lesser.
Normal or Gaussian distribution (named after Carl Friedrich Gauss) is one of the most important probability distributions of a continuous random variable. The normal distribution is important in statistics and is often used in the natural and social sciences to represent real-valued random variables whose distributions are unknown.
The normal distribution is defined by the following equation: Normal equation.The value of the random variable Y is: Y = { 1/[ σ * sqrt(2π) ] } * e-(x - μ) 2 /2σ 2 where X is a normal random variable, μ is the mean, σ is the standard deviation, π is approximately 3.14159, and e is approximately 2.71828.
