Part 2: In 1-2 pages, complete the following: 1.Define and explain the differences among mean, median, mode, and standard deviation. 2.Using the excel example & data (materials provided) , sort Column A, DRG Definition, to only show “001 – HEART TRANSPLANT OR IMPLANT OF HEART ASSIST SYSTEM W MCC” records. ◦For this part of the assignment, you will only use data from Column I, Total Discharges, and Column L, Average Medicare Payments. ◦Using excel, calculate the mean, mode, median, and standard deviation for Column I, Total Discharges. ◦Using excel, calculate the mean for Column L, Average Medicare Payments. ◦Present your findings in your paper in the chart below, or one that you have created. 3.Explain what each calculation means in terms of the data presented. (Note: The data is DRG Summary data for Medicare Inpatient Prospective Payment Hospitals for 2015.
