Chapter 22: Bivariate Analysis Assignment. Two Sample T-Test Attached Files: auto_data.xls (20.5 KB) Research Analysis Assignment Outline.docx A (15.206 KB) Using the Auto Data set, which describes a set of vehicles and their prices in the 1970s, use a bivariate model to work through the Business Research Process using the attached outline document to construct your response. Under sections where this methodology does not provide an appropriate response, state as much In this scenario you can take the perspective of an auto buyer, seller, dealer, inspector, etc. You may be interested in engine size, price or any other variable. Pick a topic of interest and use it to build out the research question and the succeeding questions using the Assignment Outline provided. Take some liberty with your ideas and build it out knowing what the collected dataset looks like. The second half of the research process, particularly the Data Processing and Analysis portiort should be constructed using the dataset provided following your declared research question and research objectives. Use some creativity but follow your research objective to the end of the assignment once it is selected. Practice using both Tableau and Excel to build out your graphs/tables/vizualizations In order for a bivariate (two sample) example to work we must select two different groups and measure them using the same variabile, in this case, use the foreign vs domestic variable Examples of questions of interest may include: Is there a difference in prices between Domestic and foreign vehicles? is there a difference in engine sites between Domestic and Foreign vehicles? Using the research question and dataset provided, answer the following questions. Provide graphics and tables where appropriate. Make an effort to explain your logic and decisions. 1) Problem Discovery a. Describe the problem. b. What exploratory technique is the best fit to identify the research question? Why? c. What is the research question? d. What do you believe the results/relationship will be? e. State the Hypothesis and the Null Hypothesis 1. In English II. In Math : (x > 3) 2) Planning Research Design a. Identify and Describe the best research method(s) to collect data for the research. b. Why would this method be best? 3) Sampling a. What type of sampling would you suggest for data collection? b. Describe the sampling technique. c. What are the benefits and drawbacks of this sampling design? 4) Data Gathering a. Describe the data set, variables and how it was obtained. b. Identify the dependent variable. c. Provide an explanatory table/graph of the data. I. This should be an interesting description that says something about the data or maybe why its important. Bar/line/pie or similar d. Descriptive Table 1. This should be a Descriptive table that include Mean, Median, Max, Min and Standard Deviation of the variable(s) li. Make it a standalone table H. But describe in in the text 5) Data Processing and Analysis a. Describe the statistical process used and why it was selected. b. Write the statistical model in equation form. c. Results Table (table) d. Is this model significant? At what level? e. Provide a table/graphic if appropriate. 6) Conclusions a. What is the conclusion of your research? (one sentence) b. How does this compare to your original belief? What bias(es) did you bring to this work? c.
