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.
