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. Application: Analyzing Frequency Distributions Assignment

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 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 or use the correct saved SPSS data file as noted in the instructions, above.

Step 2: Run descriptive/summary statistics (mean, median, mode, standard deviation, and range) for both groups 1 and 2 (medication and placebo), combined for each of the following: AGE, CHNG_CHOL, HDL, and GLYHB (be sure to save your output)

Step 3: Separate the data file by GROUP

Step 4: Run descriptive/summary statistics for each group separately for each of the following: AGE, CHNG_CHOL, HDL, and GLYHB (be sure to save your output)

Step 5: Review your SPSS output and answer each of the following questions:

Step 6: Paste all required SPSS output below.
