BTM8107-8Week 8 ApplyMANOVA andPrepare aCourse ReflectionCorrect AnswersPart A. SPSS AssignmentIn this exercise, you are playing the role of a researcher that is testing new medicationdesigned to improve cholesterol levels. When examiningcholesterol in clinical settings, welook at two numbers: low-density lipoprotein (LDL) and high-density lipoprotein (HDL). Youmayhave heard these called “good” (HDL) and “bad” (LDL) cholesterol. For LDL, lower numbersare better (below 100 is consideredoptimal).For HDL, 60 or higher is optimal.In this experiment, you will be testing three different versions of the new medication. In datafile “Activity 8.sav” you will find the following variables: group (0=control, 1=Drug A, 2=DrugB, 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 mostpromise. Perform the following analyses and paste the SPSS output into your Worddocument.1. ExploratoryData Analysis.a. Perform exploratory data analysis on the relevant variables in the dataset. When possible,include appropriate graphs to helpillustrate 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” isyour 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,includedescriptive statistics and parameter estimates. Finally, be certain to inform SPSS that youwant a post-hoc test to help you determine which drug works best.a. Is there any statistically significant difference in how the drugs perform?

b. Data consist of LDL & HDL cholesterol levels after taking medication. These drugs aredesigned in such a way that it improvescholesterol level.For LDL, numbers below 100 isconsidered optimal. For HDL, 60 or higher is optimal. Here we have calculated mean valuesto see the effect of drugs on cholesterol levels. A drug which gives LDL < 100 & HDL > 60then it is better drug ascompared to others. Drug C fulfills both conditions. It is performingbetter than other drugs. Further Multivariate analysis is done to see the effect of all thedrugs on cholesterol level.020406080100120140ControlDrug ADrugBDrug CMean levels of LDL cholestrol ofdifferent medicationMean020406080ControlDrug ADrugBDrug CMean levels of HDLcholestrol ofdifferent medicationMean
