Public Health
Your goal for this Application is to analyze the frequency distributions of data provided as an SPSS data file. A worksheet is provided for this Application, in the form of a Microsoft Word document. Download the Module 4 Application Assignment Worksheet and paste your output—the frequency distribution table—at the end of the document. Then, based on your output, answer the questions on the worksheet, typing your answers directly into the document.
To prepare for this Application, participate in the Discussion area to clarify any questions you may have about the material presented in the textbook, demonstration video, the assigned Study Questions, or the end-of-chapter exercises. Use the Module 4 Step-by-Step guide to help you complete statistical analysis in SPSS.
The Assignment:
Run data distributions on the data file provided. Complete the Module 4 Application Assignment Worksheet, pasting the frequency distributions table at the end of the document. Be sure that your completed worksheet contains your responses to all questions and your SPSS output
Submit this Application Assignment by Day 7 of Week 7.
Research ScenarioA researcher is interested in the effect of a new medication on serum cholesterol, HDL cholesterol, and glycosylated hemoglobin of adults. The researcher randomly selects a sample of 40 (20 male and 20 female) participants who have been diagnosed with high cholesterol. Assuring equal distribution of males and females, the participants are randomly assigned to one of two conditions (or groups): Following pretest measures of serum cholesterol (CHOL), High density lipoprotein cholesterol (HDL), and glycosylated hemoglobin (GLYHB), the experimental group (group 1) is given the medication for a period of six months while the control group (group 2) is given a placebo. After the six months, CHOL, HDL and GLYHB are again measured. The post-test data for each participant are provided in the Module 4 Application Assignment Data Set Excel file and can be found in the Module 4 Learning Resources. The codebook for the data provided is as follows:AGE Age in years
SEX 1 =male, 2=female
GROUP 1 =medication, 2=placebo
CHNG_CHOL change in cholesterol from pre-test to post-test
HDL High density lipoprotein at post-test
GLYHB Glycosylated hemoglobin at post-test

Step 1: Import the Microsoft Excel data file into SPSS
Step 2: Create an ungrouped frequency distribution table for each of the following:
AGE, SEX, GROUP, CHNG_CHOL, HDL, and GLYHB (be sure to save each output and paste into this worksheet document)
Step 3: Review your SPSS output and answer each of the following questions:
| QUESTION | Type answers below |
| 1. What type of variable is AGE? | ________________ |
| 2. What type of variable is SEX? | ________________ |
| 3. What type of variable is GROUP? | ________________ |
| 4. What type of variable is CHNG_CHOL? | ________________ |
| 5. What type of variable is HDL? | ________________ |
| 6. How many participants were aged 20-29 years? | ________________ |
| 7. What percent of participants were 39 years old or younger? | ________________ |
| 8. How many participants had no change in their cholesterol value? | ________________ |
| 9. What percent of participants had HDL values of 46 mg/dL? | ________________ |
| 10. How many participants had GLYHB values of 4.52 or less? | ________________ |
Step 4: Paste each required frequency distribution table below.
