Question 1: Assigned Readings:
Chapter 4. The Scientific Method: The Gold Standard for Establishing Causality
Initial Postings: Read and reflect on the assigned readings for the week. Then post what you thought was the most important concept(s), method(s), term(s), and/or any other thing that you felt was worthy of your understanding in each assigned textbook chapter.Your initial post should be based upon the assigned reading for the week, so the textbook should be a source listed in your reference section and cited within the body of the text. Other sources are not required but feel free to use them if they aid in your discussion.
Also, provide a graduate-level response to each of the following questions:
Week 3 reading (Chapter 4) is based on the Scientific Method. Please list the steps of the Scientific Method and discuss the purpose of each step. Finally, give a real-world application of the Scientific Method with an example. Please cite examples according to APA standards.
[Your post must be substantive and demonstrate insight gained from the course material. Postings must be in the student’s own words – do not provide quotes!]
[Your initial post should be at least 450+ words and in APA format (including Times New Roman with font size 12 and double spaced). Post the actual body of your paper in the discussion thread then attach a Word version of the paper for APA review]
Submitting the Initial Posting:Your initial posting should be completed by Thursday, 11:59 p.m. EST.
Response to Other Student Postings: Respond substantively to the post of at least two peers, by Friday, 11:59 p.m. EST. A peer response such as “I agree with her,” or “I liked what he said about that” or similar comments are not considered substantive and will not be counted for course credit.
[Continue the discussion through Sunday,11:59 p.m. EST by highlighting differences between your postings and your colleagues’ postings. Provide additional insights or alternative perspectives]
Evaluation of posts and responses: Your initial posts and peer responses will be evaluated on the basis of the kind of critical thinking and engagement displayed. The grading rubric evaluates the content based on seven areas:
Content Knowledge & Structure, Critical Thinking, Clarity & Effective Communication, Integration of Knowledge & Articles, Presentation, Writing Mechanics, and Response to Other Students.
Question 2: To date, you have staunchly avoided placing any advertisements on your website. However, with revenues declining, you are considering relenting on this position. Before making a full commitment, you decide to try to determine whether the presence of ads has any negative impacts on your sales. Therefore, you make a deal with an advertiser to show a 10-second pop-up ad (that pops up and plays when the site is first visited and then becomes a banner ad on the page) intermittently over a period of one month. Suppose you’ve decided to show the ad during business hours (9:00 a.m.– 5:00 p.m.), and not show the ad any other time during the month.
What are the “subjects” in this (field) experiment?
What is the treatment?
What is the relevant outcome?
Is treatment assignment random?
Suppose for each visitor to your site, whether the visitor sees the ad is determined randomly. After the month is completed, you have the following information:
Mean sales when ad was shown: $26.75
Standard deviation of sales when ad was shown: $18.21
Number of times ad was shown: 8,172
Mean sales when ad was not shown: $27.21
Standard deviation of sales when ad was not shown: $19.20
Number of time ad was not shown: 10,437
Does showing the ad affect your sales? Explain your reasoning.
Using the data from above, the advertiser claims there is evidence that running the ads may actually improve your sales. Is there evidence for this? Explain your reasoning, why or why not
