Some research situations are summarized below. For each situation, identify all variables. Then, for each variable, note the level of measurement AND whether it is an independent or dependent variable. c. Do students prefer in-person or online courses? DePaul surveys subset of 200 students, and finds differences in course modality preferences by class level (freshman, sophomore, junior, senior). d. A sociologist who studies adolescent obesity is interested in ways that video gaming habits may contribute to obesity. They work with a local high school to collect weight and height information for 500 students, and survey those students about how many hours they spend playing video games. They also examine the influence of “background” variables, including GPA, sex, and race. e. Which neighborhoods have the highest crime rates? A criminology student gathers information on all reported violent crimes (crimes per 1000 population) in every zip code within the Chicago city limits. They find that violent crime rates are related to the median home price within each zip code.
