-
Existing data analysis methods:
- Secondary data analysis: Use existing Overseas Chinese in Canada Data data such as government statistics and corporate data for analysis.
How to choose the right data collection method
Choosing an appropriate data collection method depends on the nature of the research question, the research resources, and the researcher’s preferences. When choosing a method, the following factors nee to be considere:
- Nature of the research problem: Different research questions require different methods of data collection.
- Characteristics of the research population: The characteristics of the research population will influence which method is chosen.
- Research resources: Limitations of human, material, and time resources will also affect the choice of methods.
- Availability of data: Are there existing databases or materials available?
- Ethical considerations of research: Ensure Telegram Materials that the research process complies with ethical standards.
Things to note when collecting data
- Representativeness of sample: The sample must be representative to ensure the reliability of the research results.
