To comprehend the variation and find any outliers, I examined the distribution of earnings within the departments today. To clearly illustrate the earnings spread, this required computing the standard deviation of earnings for each department and presenting the results.
I then determined the department-specific earnings standard deviation. An understanding of the earnings distribution within each department was given by the standard deviation. A larger range of incomes among the department’s personnel is indicated by a higher standard deviation. The most variable salaries are found in the Superintendent’s office, Boston Police Department, and BPS High School Renewal. Understanding the salary scale and distribution within the department may benefit from this.
