SPSS "Application: Analyzing Frequency Distributions"

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 which is to import, 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 data set “Module applic assign data_Cholesterol etc” and can be found in the module 4 . 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 below.
