Main Task: Activity 
#8You will submit one Word document for this activity. You will 
create this Word document by cutting and pasting SPSS output into Word. 
Part 
A. SPSS ActivityIn this 
exercise, you are playing the role of a researcher that is testing new 
medication designed to improve cholesterol levels. When examining cholesterol in 
clinical settings, we look at two numbers: low-density lipoprotein (LDL) and 
high-density lipoprotein (HDL). You may have heard these called “good” (HDL) and 
“bad” (LDL) cholesterol. For LDL, lower numbers are better (below 100 is 
considered optimal). For HDL, 60 or higher is optimal.In this 
experiment, you will be testing three different versions of the new medication. 
In data file “Activity 8.sav” you will find the following variables: group 
(0=control, 1=Drug A, 2=Drug B, 3=Drug C), LDL, and HDL (cholesterol numbers of 
participants after 12 weeks).Using a MANOVA, try to ascertain which 
version of the drug (A, B or C) shows the most promise. Perform the following 
analyses and paste the SPSS output into your Word document.1. Exploratory 
Data Analysis.a. Perform exploratory data analysis on the relevant variables 
in the dataset. When possible, include appropriate graphs to help illustrate the 
dataset.b. Compose a one to two paragraph write up of the data. c. 
Create an APA style table that presents descriptive statistics for the sample. 
2. Perform a MANOVA. Using the “Activity 8.sav” data set, perform a 
MANOVA. “Group” is your fixed factor and LDL and HDL are your dependent 
variables. Be sure to include simple contrasts to distinguish between the drugs 
(group variable). In the same analysis, include descriptive statistics and 
parameter estimates. Finally, be certain to inform SPSS that you want a post-hoc 
test to help you determine which drug works best. a. Is there any 
statistically significant difference in how the drugs perform? If so, explain 
the effect. Use the post hoc tests as needed.b. Write up the results using 
APA style and interpret them. Part B. ReflectionReflect on your experience 
throughout the course and how you will use your new statistical skill set in the 
dissertation phase of your degree program. Include a brief assessment of what 
you have learned. In 2-3 paragraphs, cover the following:1. What were the 
three most important concepts you learned?2. How will the material in this 
course help you in your dissertation work?3. What would you like to have 
seen covered that wasn’t or what would you have liked more practice 
with?

1. Exploratory Data Analysis. a. Perform exploratory data analysis on the relevant variables in the dataset. When possible, include appropriate graphs to help illustrate the dataset. b. Compose a one to two paragraph write up of the data. c. Create an APA style table that presents descriptive statistics for the sample. 
A new medication designed to improve cholesterol levels is being tested. There are two types of cholesterol in clinical settings that are being examined: low-density lipoprotein (LDL) or “bad” and high-density lipoprotein (HDL) or “good”. For LDL, lower numbers are better (below 100 is considered optimal). For HDL, 60 or higher is optimal. In this experiment, three different versions of the new medication are being tested to improve cholesterol levels. So, there are four groups under study: 0=control, 1=Drug A, 2=Drug B, 3=Drug C.
The descriptive statistics for the variables LCL and HCL are given below. The LCL has a mean at 97.98 with high standard deviation at 17.165 which indicates that the LCL is more scattered. The HCL has a mean at 61.42 with comparatively low standard deviation at 7.103.

The group-wise descriptive statistics of the variables LCL and HCL are presented below. This indicates that the LCL has highest mean under drug B with highest measure of deviation whereas it has lowest mean under drug C with lowest measure of deviation. There is much variation in the means of LCL under various drugs. The HCL has highest mean under drug B with highest measure of deviation whereas it has lowest mean under drug C with lowest measure of deviation. There is much variation in the means of LCL under various drugs.
