TLO1-1: Apply the six-step investigative process in
the context of a well-designed experiment.

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.

, Introduction to Financial Statements 1-3
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
B. The seven different hotels
C. The physiological health variables
D. The two groups (informed and control)
Ans: A; LO: 1.1-4; Difficulty: Easy; Type: MC
2. The researchers chose to include room
attendants from seven different hotels (as
opposed to using stricter inclusion criteria that
would limit the study to room attendants at one
particular hotel). Describe the consequences of
this decision.
Using broader inclusion criteria may ______
(increase/decrease) the amount of variation in
the observed health outcomes. However, this
decision also __________ (supports/limits)
generalizability to a larger population of room
attendants.
