Final Self-Assessment

Final Self-Assessment Question 1 Amanda is measuring the temperature. She looks at the thermometer and sees that it is somewhere between 65 and 66 degrees Fahrenheit. She is okay with the temperature in between two integers because she knows temperature is not ________ data, but temperature is _________ data.  a) Nominal, Ordinal  b) Nominal, Discrete  c) Continuous, Discrete  d) Discrete, Continuous Feedback: The correct answer is D. Temperature is not a measure that comes in increments (discrete) but is continuous as a temperature can be any number within a range. Question 2 The first stage of Davenport and Kim's Three-Stage Model of quantitative decision making is to  a) communicate the results.  b) frame the problem.  c) solve the problem.  d) None of the above. Feedback: The correct answer is B. It is important to frame the problem by understanding the environment of a problem. After that, one can solve the problem and communicate the results to others. Question 3 A manager is looking at his previous quarter and determining the causes for the sudden sales spike to gain a better understanding of the actions and outcomes. If using analytics, which kind of analytics would the manager use?  a) Predictive Analytics  b) Prescriptive Analytics  c) Descriptive Analytics  d) Proactive Analytics Feedback: The correct answer is C. The manager should use descriptive analytics because it is used to describe the characteristics of what is being studied. In this situation, the previous quarter sales would be studied. Question 4 In a study of cancer treatments, the subjects and the treatment allocator (who is also the data gatherer) are unaware of which treatment is being given to which subject. This is a ____________ study.  a) Double-Blind  b) Triple-Blind  c) Information-biased  d) Response-biased Feedback: The correct answer is A. There are two layers being blinded in this study. If the treatment allocator and the data gatherer were different people, then this would be a triple-blind study. There is no stated bias. Question 5 Adam is measuring the temperature as the lake outside his office is freezing over. He measures the temperatures in Fahrenheit ten times with the same thermometer and gets the following results: 20, 21, 21, 20, 20, 19, 19, 21, 20, 19. Is his thermometer reliable? Is it valid?  a) Reliable and Valid  b) Reliable but not Valid  c) Not Reliable but Valid  d) Not Reliable or Valid
