The student precisely described the methods selected for both primary and secondary data collection, detailing a well-structured questionnaire distributed to 97 participants, along with the use of official shopping mall websites and field observations. The student effectively justified these methods, explaining the rationale behind the chosen approach for gathering insights on shopping center preferences. Additionally, the student selected suitable techniques for collecting quality data, combining both quantitative and qualitative questions in the questionnaire. However, the student did not specify the exact time of data collection, which is necessary for contextualizing the findings. The inclusion of relevant figures, such as maps and graphs, further supports the explanation of the investigation methods.
