Answer:
A z-score can be computed for each data value. With x representing the data value, x̄ the sample mean, and s the sample standard deviation, the z-score is given by z = (x − x̄)/s. The z-score represents the relative position of the data value by indicating the number of standard deviations it is from the mean.
