Chapter 1 Intermediate Statistical Investigations Test Bank Question types: FIB = Fill in the blank Calc = Calculation Ma = Matching MS = Multiple select MC = Multiple choice TF = True-false CHAPTER 1 TERMINAL LEARNING OUTCOMES TLO1-1: Apply the six-step investigative process in the context of a well-designed experiment. TLO1-2: Partitioning variation in the response variable into variation explained by the model and unexplained variation, and measuring and reporting the percentage of variation explained TLO1-3: Assess the statistical significance of the difference between two groups on a quantitative response variable using both simulation and theory-based approaches TLO1-4: Compare more than two treatments on a quantitative response using both simulation and theory-based approaches TLO1-5: Apply Post-hoc analysis after significant F-test (pairwise differences, as well as confidence and prediction intervals for single means) TLO1-6: Understand statistical power and how it is impacted by sample size, variability within groups, number of groups, and significance level Section 1.1: Sources of Variation in an Experiment LO1.1-1: Apply the six-step investigative process. LO1.1-2: Distinguish experiments and observational studies. LO1.1-3: Review basic study design principles such as inclusion criteria and random assignment. LO1.1-4: Define terminology specific to an experimental study (e.g., treatments). LO1.1-5: Produce a Sources of Variation diagram for an experiment. Questions 1 through 3: A study published in Psychological Science in 2007 examined a possible link between mindset and health. The following is an excerpt from the abstract of the article: ―84 female room attendants working in seven different hotels were measured on physiological health variables affected by exercise. Those in the informed condition were told that the work they do (cleaning hotel rooms) is good exercise and satisfies the Surgeon General's recommendations for an active lifestyle. Examples of how their work was exercise were provided. Subjects in the control group were not given this information.‖ 1. Identify the experimental units in this study. A. The eighty-four room attendants
