The student precisely described the methods selected for both primary and secondary data collection, detailing the use of stratified sampling across 12 sites to ensure a representative sample. The student justified these methods effectively, explaining the rationale behind the use of specific tools like CO2 and sound level meters, which enhanced the quality of data collected. Additionally, the student chose suitable techniques for gathering both quantitative and qualitative data, facilitating a comprehensive analysis of environmental quality. However, the student did not specify the exact date, time, and location of data collection, which is a necessary detail. The inclusion of various figures, such as maps and screenshots from data collection tools, further supports the investigation's methodology.
