1. We have used quantitative techniques to explore questions about whether groups differ and whether variables are related. Please provide a business example for each (differences and relationships) that you might explore in your own profession. Are there business questions that do not fall into one of those groupings that you would like to test?

2. True or false? Regression helps us determine cause and effect. Explain your answer.

3. Imagine you conduct an experiment to test whether a sample of MBA students performs better in BUS 601 after having taken a course in Excel. Of these students, you are also able to group them according to who uses Excel in their jobs and who does not. Using best practices in experimentation described in class (also explained in the various Harvard Business readings), how would you conduct the experiment and draw your conclusions?

4. Please evaluate the correlation matrix below (see Canvas for matrix), assuming stock price is the response variable in a series of multiple regression equations you plan to run. If you are using this as a diagnostic tool, what are you looking for? If this was your data, how would you proceed?

5. Please describe three things you learned in this class that you believe will make you a more informed consumer of business data and statistical reporting.

In this chapter, we explore several techniques for allocation costs. Let's pretend you are on a committee to determine how much much tuition should increase per student for an upgrade in computer technology. For example, each student must purchase Excel for use in the Cost Accounting class but the technology fee is charged for each class. However, most classes do not use EXCEL. Propose an allocation basis so the university can recover the cost of this upgrade. Make specific recommendations...

Stereotypes, as we have come to understand, are assumptions that some individuals have about certain groups. Stereotypes can span across race, gender, religion, ethnicity, sexual preference, and other areas. We have also come to understand that individuals within these different groups face stereotype threat, or the risk of people feeling they are conforming to the stereotypes that exist about their social group. In your initial discussion post for this unit consider the impact that stereotype threat can have on an...
