Question and answer
What role do z-scores play in this transformation of data from multiple distributions to the standard normal distribution?
Transforming to a z-score allows you to use a single table (Standard Normal) to evaluate probabilities. Without the transformation, you would have to use calculus to determine the probabilities for each non-Normal distribution. [ ]
