Frequently Asked Questions
What is a z-score?
A z-score tells you how many standard deviations a value is from the mean. A z-score of 2 means the value is 2 SDs above the mean.
How do I interpret z-scores?
Z-score of 0 = at the mean; positive = above mean; negative = below mean. Larger absolute values = further from the mean.
