Step 1

It tells us how far a value is from the average in terms of standard deviation units. The z-score can be positive or negative, indicating whether the value is above or below the mean, respectively. A positive z-score means the value is above the mean, while a Show more…

The z-score tells us the percentage of the time that a value in a distribution occurs. It is also the number of standard deviations from the mean that a value in a distribution is. Additionally, it indicates whether a value in a distribution is above or below the mean.
