On what factors does the size of a z-score depend?
Solution
A z-score (aka, a standard score) indicates how many standard deviations an element is from the mean. A z-score can be calculated from the following formula.
z = (X - ?) / ?
where z is the z-score, X is the value of the element, ? is the population mean, and ? is the standard deviation.
