The raw data for this project originates from XXX. For this project, the
raw data was scaled and standardized several ways. First, each variable
was assigned to a category where a high value equates to a high

a low opportunity (“lower is better”).
The z-score value represents the number of standard deviations x is from the mean. The z-score calculation is:
Where “higher is better”:
Where “lower is better”:
