Normal distribution table: A comprehensive Z table showing probabilities and

A comprehensive Z table showing probabilities and areas under the standard normal distribution curve. The standard normal distribution table , or z table , provides probabilities for the standard normal distribution . The standard normal distribution is just a special case of the widely used normal distribution . The normal distribution is widely used for two reasons. The first reason is that it has a lot of real-world applications. Many everyday things, such as test scores, height, weight, rainfall and so on, are normally distributed. Secondly, the normal distribution is used frequently in the ... t Distribution Critical Values −6 −4 −2 0 2 4 6 ... χ2 Distribution Critical Values χ(ν) 2 The z-score table is used to find the probability that a random variable from a standard normal distribution will fall below a certain value. In this article, we will learn about the Z Score Table in sufficient detail and also learn how to use the Z Score Table in numerical problems.
