1.Dr. Hela is very interested in the relationship between exercise and OCD symptoms. For her study, she decides to measure exercise, which she operationally defines as the number of minutes participants report exercising during a typical week, and OCD symptoms, which she operationally defines as intensity of symptoms, using an appropriate scale. After collecting data, she discovers exercise has a negative relationship to OCD symptoms – that is, the more time participants reported exercising, the lower the intensity of their OCD symptoms. What was the control group for this study? -frequent exercisers -those with the most intense OCD -those without OCD -there was no control group in this study. 2.Loki is conducting research on the relationship between IQ and extroversion, however, those participating in the study have been told the research was exploring IQ and GPA. This is an example of: -deception -bias -role-playing -illusory correlation 3.Dr. X is is very interested in the relationship between exercise and OCD symptoms. For her study, she decides to measure exercise, which she operationally defines as the number of minutes participants report exercising during a typical week, and OCD symptoms, which she operationally defines as intensity of symptoms, using an appropriate scale. After collecting data, she discovers exercise has a negative relationship to OCD symptoms – that is, the more time participants reported exercising, the lower the intensity of their OCD symptoms. Is this study experimental or nonexperimental? -experimental -nonexperimental 4.When using a regression to analyze data and draw conclusion, researchers need to remember: -that regressions correlate data using more than one predictor but that does not necessitate a causal relationship among variables -that regressions are complex models -that regressions are causal models -that regressions are more sophisticated than bivariate correlations 5.Ellen has read a number of studies on the effect of physical attractiveness on judgments of an individual’s personality characteristics. She then writes a paper in which she categorizes the findings and draws her conclusions based on her summaries of the studies. Ellen has most likely conducted a(n) -literature review -meta-categorization -meta-analysis -categorization analysis 6.Peter and Gamora have the same opinions on the song called “Mister Blue Sky.” Gamora gives the song two thumbs up and Peter also gives it two thumbs up. Based on their ratings, we might conclude that there is … -high interrater reliability -low interrater reliability -high reactivity -low reactivity 7.A quasi-experimental design can never be -Repeated-measures -Between-subjects -Used in developmental research -Quantitative in nature 8.The more Groot studies for an exam, the lower he scores. This is an example of a negative correlation. -True -False 9.A difference between an interval scale and a ratio scale is -a ratio scale has an absolute zero point, an interval scale does not -an interval scale has an absolute zero point, a ratio scale does not -a ratio scale has equal intervals, an interval scale does not -an interval scale has equal intervals, a ratio scale does not 10. In an experiment, random assignment to conditions assures that: -All participants are equal except for the level of the independent variable -Participants are treated ethically within the experiment -The outcome of the experiment is not due to history -The sample is truly representative of the population SCIENCE HEALTH SCIENCE NURSING SOCIOLOGY 483
