In order to come up with a realistic schedule, a manager wants to know how long it usually takes an employee to complete a task. Which statistical measurement is the manager most likely to use?

The mean is the average: add the task completion times and divide by the number of employees or observations. It gives the manager a typical overall time for scheduling. The median is the middle value, the mode is the most frequent value, and the sum is the total of all times rather than a usual time.
