This document contains the tables for the standard normal, \(\chi^2\), Student’s \(t\) and \(F\) distributions for use in statistical inference and applied probability problems. The intended contribution of the writing is to provide researchers and practitioners with practical tools for verifying normal distribution. A standard normal table, also called the unit normal table or Z table, is a mathematical table for the values of Φ, which are the values of the cumulative distribution function of the normal distribution.It is used to find the probability that a statistic is observed below, above, or between values on the standard normal distribution, and by extension, any normal distribution.
