Standard normal table:
A standard normal table is often known as a Z table or a unit normal table.
It's a mathematical table for the values of normal distribution's cumulative distribution function.
It is used to determine the likelihood of observing a statistic below, above, or between values on the standard normal distribution, and by extension, any normal distribution.
Because there are an unlimited number of normal distributions and probability tables cannot be written for each, it is usual practice to convert a normal to a standard normal and then use the standard normal table to obtain probabilities.
