What percent of participants were 39 years old or younger?

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.
1. In the Viewer pane, select File > Export.
2. Under “Objects to Export,” select All.
3. From the “Type” drop-down list, select Word/RTF (*.doc).
4. 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.

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.

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
