Research Qualitative and Quantitative

When talking about qualitative and quantitative research it sound very academia. Before start my DBA journey, working in industry this is what I feel too. This semester I am taking my 3rd research subject is university which is Qualitative and Quantitative Analysis. This is what i learned.When we are in is process of finding things… its usually using quantitative, quantitative or both. This is how human being thinking process are. Let see the definitions.

Quantitative Research

Quantitative research is defined as a systematic investigation of phenomena by gathering quantifiable data and performing statistical, mathematical, or computational techniques. The research aim is an in-depth, contextual analysis of a phenomenon.  These methods are very good for answering the what and who questions.

Qualitative Research

Qualitative research focuses on obtaining data through open-ended and conversational communication. This method is not only about “what” people think but also “why” they think so. The research aim is to produce generalizable results that show prevalence, incidence, and statistical relationships between variables and causation. These methods are well suited to answering why and where questions, but may lack a deep understanding of a phenomenon, particularly if the research area is of a sensitive nature.

Comparison Quantitative and Qualitative

Quantitative Qualitative General framework

• Seek to confirm hypotheses about phenomena
• Instruments use a more rigid style of eliciting and categorizing responses to questions
• Use highly structured methods such as questionnaires, surveys, and structured observationSeek to explore phenomena
• Instruments use more flexible, iterative style of eliciting and categorizing responses to questions
• Use semi-structured methods such as in-depth interviews, focus groups, and participant observation

Analytical objectives

• To quantify variation
• To predict causal relationships
• To describe the characteristics of a population
• To describe variation
• To describe and explain relationships
• To describe individual experiences
• To describe group norms

Question format

• Closed-ended
• Open-ended

Data format

• Numerical (obtained by assigning numerical values to responses)
• Textual (obtained from audiotapes, videotapes, and field notes)

Flexibility in study design

• Study design is stable from beginning to end
• Participant responses do not influence or determine how and which questions researchers ask next
• Study design is subject to statistical assumptions and conditions
• Some aspects of the study are flexible (for example, the addition, exclusion, or wording of particular interview questions)
• Participant responses affect how and which questions researchers ask next
• Study design is iterative, that is, data collection and research questions are adjusted according to what is learned
