lOMoAR cPSD| 57819357 W G U C207 O A Final Self - Assessment 150 Q&A 2025 - 202 6 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 d ata. • 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 quar ter and determining the causes for the sudden sales spike to gain a better understanding of the actions and outcomes.

lOMoAR cPSD| 57819357 • • 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) Trip le - 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 Feedback: The correct answer is B. The thermometer consistently gives about the same number for the freezing point and therefore is reliable. It is not valid because it does not accurately measure what it is trying to measure. We know this because we know water freezes at 32 degrees Fahrenheit. Question 6

He gets the following responses: 70 ,000; 450,000; 2,000; 130,000; 3,000,000; 75,000; 200,000; 800,000; 150,000; and 210,000. Is this survey reliable? Is it valid? • a) Reliable and Valid • b) Reliable but not Valid • c) Not Reliable but Valid • d) Not Reliable or Valid Feedback: The correct answer is D. The answers are not consistent and do not accurately measure the number of people. Therefore it is not reliable or valid. Question 7 Harry is doing a survey of the city of Los Angeles' population. He is wondering everyone's favorite food. He sends out a survey to all of the renters in the city and receives basically all of the surveys back in the mail. What is the flaw in this experiment? • a) Small Sample Size • b) Blinding • c) Truly Representative Sample • d) Association vs. Causation Feedback: The correct answer is C. This does not represent the entire population that Harry is concluding about as he did not get responses from the other samples such as homeowners in Los Angeles. Question 8 Tom Brady is on the street in Chicago. He is asking anyone he meets if they prefer Tom Brady or Peyton Manning. The survey results show that people greatly prefer Tom Brady. What is the flaw in this experiment? a) Small Sample Size • b) Truly Representative Sample • c) Response Bias
