What is z value in statistics?

In: Math and Arithmetic, Statistics [Edit categories]

Answer:

A z-value is usually the result of a translation from a normally-distributed variable. Through the translation into a standard normal variable (with a mean of zero and a variance/standard deviation of one), the tables available in all statistical texts and all over the interweb can be used to calculate probabilities using the so-called "z-tables", or the fractiles of the standard normal distribution.
