Both qualitative and quantitative methods of user research play important roles in product development.
Qualitative research relies on words to explain research findings; it may use interviews or focus groups.
Quantitative research involves creating a hypothesis and identifying statistics to explain research findings. Using quantitative research has many advantages. For example, quantitative research allows a researcher to objectively detail evidence. However, quantitative research also has disadvantages.
Analysis Qualitative research relies on specific evidence rather than generalized research. For example, qualitative research allows a researcher to use a case study to illustrate a phenomenon.
Qualitative research often involves cross-case comparisons. Objectivity Qualitative research tends to cause a researcher to become immersed in the research topic. For example, a researcher using qualitative research may conduct in-depth interviews, interact with participants and rely on her own observations.
A researcher using quantitative research methods remains separated from the subject matter. The researcher remains objective when conducting research. Instead of conducting in-depth interviews, a researcher may use analysis and questionnaires to test a hypothesis. An advantage of using quantitative research is that the researcher remains more objective while proving or disproving a hypothesis.
Time Consuming Quantitative and qualitative research both encompass planning before conducting or analyzing research. Quantitative research, however, involves more planning, which becomes a disadvantage.

For instance all aspects of a research study must be carefully designed before collecting any data. A researcher needs a concrete hypothesis and needs to know the type of research involvedsuch as questionnaires and test questions.
With qualitative research, the design typically emerges as the research study develops. Data Driven Quantitative research depends on data and involves testing a hypothesis, but it can miss contextual details.
Instead the researcher depends on numbers and statistics to prove a hypothesis. Cite this Article A tool to create a citation to reference this article Cite this Article.Analyzing and Interpreting Information.
Analyzing quantitative and qualitative data is often the topic of advanced research and evaluation methods courses. And because qualitative interviews are designed to elicit detailed information, they are especially useful when a researcher’s aim is to study social processes, or the “how” of various phenomena.
Chapter 3 Common Qualitative Methods. In this chapter we describe and compare the most common qualitative methods employed in project evaluations. 3 These include observations, indepth interviews, and focus groups. We also cover briefly some other less frequently used qualitative techniques.
8-step procedure to conduct qualitative content analysis in a research A study by Ary et al. () categorized qualitative research/method into two distinct forms. Firstly participant observation, where the researcher is a participant of the study. Journal of Health, Social and Environmental Issues () Vol 6, No 1 45 Abstract A new framework for critiquing health-related research is presented in this article.
