Disсussion: Chаptеr 8 A researcher designs an intervention that aims to reduce alcohol use among high school students. The researcher provides the intervention to students in one 12th grade classroom and compares their alcohol use to that of students in another 12th grade classroom who do not receive the intervention. Alcohol use is measured with a questionnaire completed by all participating students before and after the intervention. Random assignment to conditions was not possible because the researcher could not assign students to different classrooms. This is an example of an experimental pretestposttest control group design. True or False? Please explain your reasoning. Discussion: Chapter 9 Select a research problem and discuss how you could use the different sampling methods described in the textbook. Provide examples for all of the different types of probability sampling and nonprobability sampling. What is the effect of the sampling method on the way you view your research problem? Discussion: Chapter 10 Imagine that you are a social worker working at Western New Mexico University. One of your assignments is to conduct a survey of parents and their preferred modes of communication with their child’s teachers. Given the demographic profile of this school, what challenges might you encounter if you used a questionnaire? How might you increase your response rate?
