Departmental Disparity The figure shows the salary for 60 employees of an organization. The organization is divided into four departments-Production (P), Administration (AD), Sales (S), and Accounts (A).
In the Administration department, the potential outlier is CEO, and in the Accounts department, the potential outlier is CA.
Why is it best to compare medians and interquartile ranges for these data, rather than comparing means and standard deviations?
List the appropriate median salary for each department; for example, the median for the Production department is between 15,000 and 20,000.
Also, arrange the departments from lowest interquartile range (on the left) to the highest.
