Normal distribution table: The standard normal distribution table

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 ... A comprehensive Z table showing probabilities and areas under the standard normal distribution curve. Find the cumulative probabilities for z-values from -3.4 to 3.4 in this table . The table also shows the probabilities for negative z-values and the corresponding positive z-values. Find the area under the standard normal curve for any value of Z. See the graph, the formula and the table of values for 0 to Z and Z onwards.
