Exercise # 1 Instructions:
1. You may download the dataset from the link below. This dataset provides information about hospitals in 2011 and 2012. Before you do that however consult the additional instructions that I provided to you in 4 PDF email attachments. ([a]. Ex 1 – Additional Instructions. [b] Ex 1 – Instructions t-Test to compare means [c] Ex 1 – Example t-Test Output. [d] Ex 1 – Example Output – Graphs).
2. Analyze the data, using these instructions. Your objective is to use the results of your analysis to create “summary statistics” (Count (N), Mean, and Standard Deviation) for each hospital characteristic and each year (2011 and 2012) and complete Table 1 (template below). You should then create any meaningful graphs (using Excel) to summarize your findings and to write a short paragraph summary report describing your findings.
3. Your report may be in WORD format, with the tables you create in Excel copied and pasted in WORD. Submit your report to the appropriate folder.
Table 1. Descriptive statistics between hospitals in 2011 & 2012
| Hospital Characteristics | 2011 | 2012 | Difference between 2011 & 2012 | ||||
| N | Mean | St. Dev | N | Mean | St. Dev | t-Value (Pr<|t|) | |
| 1. Number of Hospital beds | |||||||
| 2. Number of paid Employees | |||||||
| 3. Number of non-paid Employees | |||||||
| 4. Total hospital costs | |||||||
| 5. Total hospital revenues | |||||||
| 6. Available Medicare days | |||||||
| 7. Available Medicaid days | |||||||
| 8. Total Hospital Discharges | |||||||
| 9. Medicare discharge | |||||||
| 10. Medicaid discharges | |||||||
| 11. Hosp Cost Per Discharge | |||||||
Exercise 1 Findings: Based on your findings, in which years did the hospitals have better performance? Please write a short paragraph and describe your findings. Make sure to attach plot(s) or graph(s) of the information to your report.
