In terms of Health ratings, compilinginformation about BMI, heart rate, blood pressure, etc., is allpart of the
A.grouping variable
B.operational definition
C.construct
D.all of these
In this data set, the variableof Gender is ona scaleof measurement and would bea .
a.Nominal // grouping variable
b.cannot be determined
c.Ratio/interval // dependent list
d. Ordinal // factor
In this data set a control analysis would involve examining?
A.both analyses that examine the influence of ACTIVITY on Hrate1and Wrate 1
B.The influence of ACTIVITY on Wellness ratings (i.e., Wrate1)at the beginning of the study (prior to any training)
C.The influence of ACTIVITY on Health ratings (i.e., Hrate1) atthe beginning of the study (prior to any training)
D.None of the these, control analyses are only for correlationsand ANOVA’s
In this data set, the variableof age is ona scaleof measurement
A.Cannot be determined
B.Ordinal
C.Ratio/interval
D.Nominal
In terms of Wellness ratings, thegeneral notion of how individuals are feeling health wise isthe
A.operational definition
B. factor
C. null hypothesis
D. construct
Based on the definitions provided in class, in this data set,assignment to the different training groups (orthe ACTIVITY variable) to study itsinfluence on health makes this study design a
A. Quasi experiment
B. All of the these
C. True experiment
D. A correlational study
If the researcher wanted to explore the relationship ofgender AND type of activity on eitherhealth ratings or wellness ratings then the type of test statisticto use would be
A. none of these, a researcher cannot ask that type of researchquestion
B.paired samples t-tests for activity and independent samplest-test for gender
C. independent samples t-tests for both gender and activity
D. use a 2 (gender) X 3 (activity) factorial ANOVA
In this data set a Pearson correlation between Age and Wrate1is but a Pearsoncorrelation between gender and Wrate1is .
A. appropriate because ratio-interval scales are used // isinappropriate
B. not helpful to understanding factors that influence health //helpful tounderstanding PS
C. a paired samples t-test // an independent t-test
D.full of assumptions // not full of assumptions
Following a pilot study with a survey, researchers are exploring the relationship of prosocial behavior & health & well being. One feature of prosocial behavior is that it can generate positive emotions which are believed to have beneficial effects on health. To explore this relationship, the researchers design a study in which the participants are randomly assigned to 1 of 3 groups that vary in prosocial activity (ACTIVITY): 1-a group that has no specific intervention (control), 2-a group that is instructed to engage in positive emotional thoughts for one month; and 3-a group that works with a specific volunteer group for 5 hours a week for a month. The following information was collected: Age: recorded in the number of years of age reported on the survey; Gender: male (1) or female (2) as reported on the survey Health rating (Hrate): This is a composite of several measures of health including BMI, heart rate, blood pressure, cholesterol & triglycerides; and lung function. It is on a 0 (very poor health) to 100 (excellent health). Most physicians agree that a rating of 30 on this scale warning sign of serious health issues and a rating of 50 is acceptable health. This data is collected at the beginning of the study (Hratel) and at the end of the study (Hrate 2) Wellness rating (Wrate): Participants are asked to rate themselves in terms of how they are feeling health wise over the last week. This wellness rating is on a 0 (I feel terrible & am worried about my health) to 10 (I feel tremendous & I am in great shape). Physicians recognize that a rating of 3 or lower indicates that follow up measures should be taken and a rating of 6 or better indicates individuals have a positive sense of wellness.
