The student precisely described the methods selected for both primary and secondary data collection, detailing the systematic sampling method and its implementation across 15 sites to ensure representativeness. They justified their chosen methods by explaining how the systematic sampling allowed for a wide spatial range, enhancing the identification of spatial patterns, and supported their analysis with both quantitative and qualitative data types. The student chose suitable techniques, including footfall counts and environmental quality surveys, which contributed to a comprehensive understanding of tourism's impact on Tai O. However, they did not state the exact time of data collection, which is a necessary detail. The student effectively included figures such as maps and photographs to clarify the methods of investigation.
