**Z-Score:** It is a way to compare individuals in a set of data. The score measures how outstanding an individual is relative to the mean of a population (data) using the standard deviation for that population to define the scale. Z-scores may be positive or negative.

**Percentile:** It divides the data set into 100 equal parts instead of four equal parts like quartiles. It describes the relative standing of an individual in a population by mentioning the rank position of the individual. They use the median as the average (50th percentile), while z-scores use the mean as average (z-score of 0). Percentiles are always integers (e.g., 85th, not 85.7th percentile, traditional exam marks of a student).

Both z-scores and percentile are different ways to compare individuals in different populations. Enter a Z-critical value in the **online z score to percentile calculator** and get the percentile from Z score within the blink of eye.
