How to choose research methods

The choice of research method depends on your research questions, objectives, and disciplinary characteristics. There is no "best" research method, only "most suitable" ones.

Quantitative research is suitable for answering "how much" and "to what extent" questions; qualitative research is suitable for answering "why" and "how" questions. Mixed methods can answer both types.

Quantitative research methods

• Survey method: Most commonly used quantitative data collection method
• Experimental method: Verify causal relationships by controlling variables
• Secondary data analysis: Analyze existing datasets
• Econometric models: Regression analysis, time series analysis

Qualitative research methods

• In-depth interviews: Suitable for exploratory research
• Focus groups: Suitable for collecting multiple perspectives
• Case study: In-depth analysis of specific phenomena
• Fieldwork: Observation and recording in natural settings

Survey design key points

• Questionnaire structure: Opening statement, screener questions, basic information, core questions, closing remarks
• Question design: Avoid double negatives, leading questions, and sensitive questions
• Scale selection: Likert scale is most widely used
• Pilot test: Test with small sample before formal survey

Data analysis methods

• Descriptive statistics: Mean, standard deviation, frequency analysis
• Inferential statistics: t-test, ANOVA, chi-square test
• Regression analysis: Linear regression, logistic regression
• Structural equation modeling: Verify complex variable relationships

Frequently asked questions

Can liberal arts students use quantitative research methods?

Of course. Quantitative research methods are widely used in education, management, sociology and other humanities and social sciences. Survey is the easiest quantitative research method to start with.

How large should the sample size be for quantitative research?

This depends on analysis complexity. General regression analysis requires 100+ samples; structural equation modeling requires 200-500 samples.

Do I need to discuss research methods with my advisor?

Strongly recommended. Research method selection should consider not only academic standards but also advisor research background and preferences, and school facility support.
