SPSS Application: Analyzing Frequency Distributions

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 (attached), 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.

The Assignment:

Run data distributions on the data file provided (attached). Complete the Module 4 Application Assignment Worksheet (attached), 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.

PUBH6032 – Module 4 Application Step-By-Step Guide
Step 1: Import the Microsoft Excel data file into SPSS
1. Save the Module 4 Application dataset (Excel file) to your computer.
2. Open SPSS, select “Open an existing data source,” highlight “More Files,” and click OK.
3. Look to the bottom of the Open Data dialog box and use the “Files of type” drop-down
menu to select Excel file (instead of SPSS). Locate the folder where you saved the
Module 4 Application dataset Excel file, highlight it, and click OK.
4. In the Opening Excel Data Source dialog box, make sure “Read variable names from the
first row of data” is checked and click OK.
5. The data should now be imported into SPSS.
Step 2: Create an ungrouped frequency distribution table for each of the following:
AGE, SEX, GROUP, CHNG_CHOL, HDL, and GLYHB
1. Click Analyze > Descriptive Statistics > Frequencies.
2. Highlight AGE, SEX, GROUP, CHNG_CHOL,HDL, and GLYHB. Click on the arrow button to
move them over to the “Variables” box.
3. Make sure the “Display Frequency Tables” box is checked.
4. Click OK.
Step 3: Review your SPSS output and answer each of the following questions:
1. Types of variables – Click on Variable View and review the Measure column. Note that
scale = quantitative and nominal = categorical.
2. How many? – Manually add up the frequency column.
3. What percent X years or younger? – Review the cumulative percent column.
4. What percent? – Review the valid percent column.
Step 4: Paste each required frequency distribution table below.

4.
In the Viewer pane, select File > Export.
Under “Objects to Export,” select All.
From the “Type” drop-down list, select Word/RTF (*.doc).
In “File Name,” give the output a unique name (e.g., OUTPUT_Module4). (Note the file
folder where the Word document will be saved. The default is typically C:\Documents.)
5. Click OK to generate the Word file.
*Now you can cut-and-paste the information from this Word file into the Module worksheet.
You should also save the SPSS file you created for future assignments.

PUBH6032 – Module 4 Application Assignment Worksheet
SPSS Frequencies
Instructions
For this assignment, you create and analyze frequency distributions of data provided as
a Microsoft Excel file. Import the data into SPSS using the techniques described in
Module 3, and then run frequency distribution tables, as instructed below, in SPSS.
Note: It is recommended that you save the SPSS data file as you will use the same file
for Modules 5 and 6 application assignments. Type your answers to all questions
directly into the worksheet, and paste the required frequency distributions table at the
end of this document.
Submit this Application Assignment by Day 7 of Week 7.
Research Scenario
A 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:
