A normal quantile is a way to measure how many standard deviations away from the mean a particular data point falls. It is an important statistical concept that is often used in data analysis and interpretation. However, there are several synonyms that can be used to describe this concept including Z-score, standard score, standard value, and standard normal deviate. Each of these synonyms is used to represent the same fundamental idea of measuring how far a data point is from the mean in standard deviation units. Regardless of which synonym is used, understanding and interpreting normal quantiles is a critical skill in statistical analysis.
