Textbook Question
Chapter 1, Problem 17P
Ford and Torok (2008) found that motivational signs were effective in increasing physical activity on a college campus. Signs such as 'Step up to a healthier lifestyle" and "An average person burns 10 calories a minute walking up the stairs" were posted by the elevators and stairs
in a college building. Students and faculty increased their use of the stairs during times that the signs were posted compared to times when there were no signs.
a. Identify the independent and dependent variables for this study.
b. What scale of measurement is used for the independent variable?

In this same passage, answer the third question to the problem.
A study examined the relationship between a nurse's assessment of a patient's facial expression and his or her
self-reported level of pain. Data for 89 patients are summarized below:
Self-Report
Facial Expression No Pain Pain
No Pain
17
40
Pain
3
29
We'd like to determine if there is evidence of an association between a facial expression that reflects pain and
self-report pain, because dementia patients do not always give a verbal indication that they are in pain.
By using SPSS or Minitab, design the appropriate test and generate the data analyses. Relate the results of the
test to the research question and conclude the findings.
A recent study randomly selected women from various countries around the world and collected information about diet and health. The women who at a Paleo diet had lower rates of Osteoporosis when compared to the other women in the study.
A. Which is the explanatory variable and why.
B. Which is the response variable and why.
C. Write a conclusion appropriate for this type of study that describes the relationship between the explanatory and response variables.
