First, determine the probability of succe. Secondary, we calculate statistics with one of tab_stat_* functions. Most statistical tests require that the data are normally distributed; in applying these tests, instead of verifying whether the data set is indeed normally distributed, researchers tend to assume normality. 5. 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. As with academic writing, it is also just as important to structure tables so that readers can easily understand them.
