Standard Normal Probability Table Calculator. Z score formula and explanation with examples as well as a Z table with key values. Standard normal probability table calculator Dennis SaboiStockGetty Images By. Normal distribution or Gaussian distribution named after Carl Friedrich Gauss is one of the most important probability distributions of a continuous random variable. The normal distribution table found in the appendix of most statistics texts is based on the standard normal distribution which has a mean of 0 and a standard deviation of 1To produce outputs from a standard normal distribution with this calculator set the mean equal to 0 and the standard deviation equal to 1.
This calculator determines the area under the standard normal curve given z-Score values. Z statistic calculator with support for normal distributions with custom mean and sigma. Standard Normal Distribution Table. Z score calculator to calculate a Z score from a raw score. Using the information provided or the formula Y 1 σ sqrt 2π e - x μ22σ2 determine the normal random variable. A z-table also known as a standard normal table or unit normal table is a table that consists of standardized values that are used to determine the probability that a given statistic is below above or between the standard normal distribution.
