## Why is the z-score important?

Z-scores are important because they offer a comparison between two scores that are not in the same normal distribution.

An observation 6 standard deviations above the mean is more extreme than one only 4 standard deviations about the mean, but both are beyond 3 decimal places of accuracy for the percentile, so the Z-score can more accurately summarize their relative extremity.

## What are the disadvantages of z-scores?
