<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.

A is the answer it makes sense
False. <span>IQ is <em>not</em> one of the best predictors of success and happiness in life.
Intelligent Quotient or IQ is a test that rates one's intelligence levels (visual, spatial, numerical, mechanical and verbal intelligence) through a written test. The average IQ score indicating average intelligence levels is from 90-115. IQ is not a reliable predictor </span>of success and happiness in life, because intelligence does not necessarily equate success. For instance, a person might have high IQ, but might not have a good job or good interpersonal connections, due to which the person is neither happy nor successful.
