How Does Qualitative Interviewing Differ from Quantitative Interviewing

Question

Examlex · Accepted Answer

The Answer is Qualitative interviewing and quantitative interviewing are two distinct methods used in research to gather data, and they differ in several key ways:

1. Purpose:
- Qualitative Interviewing: The purpose is to explore complex phenomena and understand the depth, meaning, and complexity of certain issues. It aims to gather rich, detailed insights into people's thoughts, feelings, and behaviors.
- Quantitative Interviewing: The purpose is to quantify variables and measure relationships between them. It seeks to produce generalizable findings that can be expressed in numbers and statistics.

2. Nature of Data:
- Qualitative Interviewing: Produces non-numerical data, such as words, phrases, and narratives. The data is descriptive and interpretive.
- Quantitative Interviewing: Produces numerical data that can be quantified and subjected to statistical analysis.

3. Interview Structure:
- Qualitative Interviewing: Often uses semi-structured or unstructured interviews with open-ended questions that allow respondents to express their views in their own words. The interviewer may probe deeper based on the responses.
- Quantitative Interviewing: Uses structured interviews with closed-ended questions that require respondents to choose from a set of predefined responses. The questions are standardized to ensure consistency across interviews.

4. Sample Size:
- Qualitative Interviewing: Typically involves a smaller sample size, as the focus is on obtaining depth of understanding rather than breadth.
- Quantitative Interviewing: Usually requires a larger sample size to ensure the statistical significance of the results and to allow for generalization to the broader population.

5. Analysis:
- Qualitative Interviewing: Data analysis involves coding and interpreting the data to identify themes, patterns, and insights. It is an iterative and subjective process that requires careful consideration of the context and the participants' perspectives.
- Quantitative Interviewing: Data analysis involves statistical procedures to test hypotheses, calculate averages, determine correlations, and make predictions. It is a more objective process that focuses on quantifiable measures.

6. Flexibility:
- Qualitative Interviewing: There is greater flexibility in the interview process, as the interviewer can adapt questions based on the conversation flow and explore unexpected topics that arise.
- Quantitative Interviewing: There is less flexibility, as the structured nature of the interview requires sticking to a predetermined set of questions.

7. Outcome:
- Qualitative Interviewing: The outcome is a nuanced understanding of the research topic, with detailed insights into participants' experiences and perspectives.
- Quantitative Interviewing: The outcome is a set of numerical data that can be used to make general statements about the population being studied.

In summary, qualitative interviewing is about exploring and understanding the richness and complexity of human experience, while quantitative interviewing is about measuring and quantifying aspects of that experience to draw conclusions about a larger population. Both methods have their strengths and are often used complementarily in mixed-methods research to provide a more comprehensive understanding of a research question.
