Using the DeFronzo research study , break down the study into its corresponding research components. Answer each of the following six questions below based on each separate research component. Ensure that your responses are substantial. Utilize your textbook as needed to assist you in responding to these questions. Provide full references for any sources used at the end of the worksheet. Format your sources according to APA formatting.
1. Identify the research purpose of this study (as identified in your textbook in Chapter 1). What is DeFronzo’s central research question?
2. Identify the independent variable(s). Identify the dependent variable(s). Identify any additional independent variables used as control variable(s).
3. Identify the general population of subjects being used. Based on this population, what sampling strategy did DeFronzo employ (probability or nonprobabiliy)? Based on the sampling strategy, identify the sampling technique and describe the resulting sample of subjects (people, places, or things) analyzed in the study.
4. Identify the research design used (true classic, quasi-experimental, or non-experimental). Explain why this particular design was utilized in comparison to other possible designs.
5. Identify the data collection methods (asking questions, field research, utilizing existing data, and/or a combination) used in this study to measure the variables.
6. Assess the validity (accuracy of the findings) and reliability (consistency of the findings) of this research study based on the research components utilized by the author.
