Comparison: Quantitative Research, Qualitative Research & Mixed Method Research

 

Aspect	Quantitative Research	Qualitative Research	Mixed Method Research
Research Focus	Numbers, measurable data	Text, narratives, non-numeric data	Combines both quantitative and qualitative approaches
Research Question	Generally structured and specific	Open-ended, exploratory	Can be structured or open-ended, depending on the design
Data Collection Methods	Surveys, experiments, structured interviews	Interviews, observations, focus groups	Combination of surveys, experiments, interviews, observations, etc.
Sample Size	Large samples, statistical significance	Small samples, in-depth understanding	Can vary, depending on the research design and goals
Data Analysis	Statistical analysis, numerical patterns	Thematic analysis, content analysis	Both statistical analysis and qualitative analysis techniques
Generalization of Findings	Often aims for generalizability	Context-specific, not always generalizable	Can provide both generalizable and context-specific findings
Validity and Reliability	Emphasizes reliability and validity through standardized measure	Reliability is context-specific, validity through triangulation	Emphasizes both reliability and validity, using multiple methods
Role of Researcher	Objective, aims for neutrality	Subjective, researcher's presence acknowledged	Can be both objective and subjective, depending on the research design
Time Frame	Typically shorter time frames for data collection and analysis	Longer time frames for in-depth understanding	Can vary, depending on the research design and methods used
Purpose	To test hypotheses, establish patterns	To explore, understand social phenomena	To gain a comprehensive understanding by combining strengths of both approaches
Examples	Surveys on customer satisfaction, experimental studies	Ethnographic studies, case studies	Sequential explanatory designs, concurrent designs
