( Obesity in America

I’m working on a health & medical project and need an explanation to help me understand better.

Based on the topic you chose in Unit I ( Obesity in America) you will describe the research design and methodology you plan to use to complete your research (remember this is a hypothetical research study that you will not conduct). You will include and discuss the type of data you will collect and consider the following questions:

• Describe the three types of research designs, and explain what method you will use to collect data (qualitative, quantitative, mixed methods).
• Why did you choose this approach?
• What type of tool (i.e., survey, interview, observation) will you use to collect data?
• Explain why you will use that type of data collection tool.
• Explain how you will ensure internal and external validity in your research project.
