Directions:
After you have downloaded the SPSS program to your computer, completed the assigned readings, and viewed the assigned videos, use the data provided in the topic Resources, “HCUP State Inpatient Databases (SID) File Composition – Number of Discharges by Year,” and appropriate statistics to address the following:
- Determine the statistics for discharges in 2018 as follows: Mean, Median, Mode, Standard Deviation, Minimum, and Maximum.
- Describe the data distribution using the bell curve as follows: Create a histogram with discharges (axis X) and frequencies (axis Y).
SPSS Output
- Open SPSS and open a new database.
- Go to the Variable View.
- In the first row, label the name as State. Enter State as the Label Field. In the Values drop down, enter numerical values for each state label (e.g., 1 = AK, 2 = AR, etc.).
- In rows 2 through 10, label the name as Year_2012 through Year_2020. Enter the applicable year (e.g., 2012, 2013, etc.) in the Label Field.
- Go to the Data View and enter the data. Use numbers for the states in the first column. Enter the discharges for each applicable year (2012 – 2020) and align to the respective state. Save this data set. You will use this same data set in Topic 4.
- Go to the menu and click Analyze. Click Descriptive Statistics, then click Frequencies, and add Year_2018 to the field. Click Statistics and click mean, median, mode, std. deviation, minimum, and maximum. Click continue. Click Charts and select Histograms. Click show normal curve on histogram. Click continue. Click OK. Review and save the Output.
Summary
Create a histogram of the discharges graphed. Determine if the data are normally distributed or skewed according to the bell curve. Write a 250-500-word summary of your analysis and results. Attach the histogram and the SPSS statistical output to the appendices of your paper.
