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.
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 data set "Module 4, 5, and 6 applic assign data_Cholesterol etc" 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
What type of variable is AGE?
What type of variable is SEX?
What type of variable is GROUP?
What type of variable is CHNG_CHOL?
What type of variable is HDL?
How many participants were aged 30-39 years?
What percent of participants were 49 years old or younger?
How many participants had no change in their cholesterol value?
What percent of participants had HDL values of 43 mg/dL?
How many participants had GLYHB values of 4.67 or less?
Step 4: Paste each required frequency distribution table.
