<u>Question 1</u>
The correct answer is: "The researchers administered a questionnaire to obtain their data without trying to influence an explanatory variable of the study".
An observational study is one in which the researcher observes the effect of a variable without manipulating the conditions that surround the exposure or the subjects who are exposed to it. In this example, he simply hands out questionaires to the 353 individuals that compose the sample drawn from the population of interest: 12-year old teenagers.
<u>Question 2</u>
The correct answer is: "a cohort study".
The researcher is interested on a population group where all the components share a common characteristic (12-year old) and therefore they all belong to the same cohort. Subsequenly, he evaluates the differences between the ones who have been exposed to the explanatory variable (having a video console in the bedroom) and those who have not.
Answer:
Role strain.
Explanation:
As the exercise exemplifies, role strain occurs when a person has a difficulty meeting the responsibilities of a particular role in her or his life. A role is a set of expected behaviors and obligations a person has taken or has inherited. In this case, Janelle has role strain as a mother, given that she can't always act as she wants to and sometimes has as she is meant to do because of her role: to be firm, when she wants to be kind, altough she does it for the good of her children. When expectations are incompatible as these are, it is most likely to be facing role strain.
