The student clearly states the independent and dependent variables in the research question, identifying annual temperature and precipitation as the independent variables and the number of Cystic Fibrosis patients receiving oxygen therapy as the dependent variable. However, the research question lacks clarity regarding the method of analysis, as it does not specify how the dependent variable will be measured. While the student provides relevant background theory and discusses the choice of aspects such as the number of trials and scope, there are several areas needing improvement, including the explanation of how measurements are taken, the sampling technique, and the identification of controlled, safety, ethical, and environmental issues. The methodology is generally well-structured and free from irrelevant information, but it requires more detail for reproducibility.
