1. There are limited studies on the mother's incarceration and her child's risk for foster care placement. For example, prior studies had compared the foster care records of children with their mother's criminal histories and found that most mothers (85%) had lost their custody before they were arrested or went to jail. As a researcher, you have been asked to conduct an extensive study focusing on mothers incarcerated in Texas juvenile institutions from 2015-2020. You are tasked with addressing the following question: Question: Do families in which a child is removed before the mother's incarceration differ in terms of poverty, unemployment, child maltreatment, drug use, and prior incarceration from families in which the child is removed after the mother is incarcerated? In designing the study, you should carefully address the following issues in detail: a. Identify the target population. b. Discuss one type of sampling you would use and why. C. Describe the research design you would select, and explain why you would use that design? d. List the variables that you would study and how you would measure those variables
