So, total probability equals to 0.5+0.2642=0.7642. 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. Download Z Score Table. stream Z-score table tells the total quantity of area contained to the left side of any score or value (x).
