![]() ![]() The values within the table are the probabilities corresponding to the table type.The label for columns contains the second decimal place of Z.The label for rows contains the integer part and the first decimal place of Z.Z tables typically follow the layout described below This equates to the area of the distribution above Z. Complimentary Cumulative gives a probability that a statistic is greater than Z.This equates to the area of the distribution below Z. Cumulative gives a probability that a statistic is less than Z.Cumulative from Mean gives a probability that a statistic is between 0 (mean) and Z.Z Tables use at least three different conventions: Since probability tables cannot be printed for every normal distribution, as there are an infinite variety of normal distributions, it is common practice to convert a normal to a standard normal and then use the standard normal table to find probabilities. 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. A Z table, is a mathematical table for the values of Φ, which are the values of the cumulative distribution function of the normal distribution. ![]()
