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. 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. Quantitative research depends on data and involves testing a hypothesis, but it can miss contextual details.
For example, a researcher doesn't provide a detailed description when using quantitative research. Instead the researcher depends on numbers and statistics to prove a hypothesis. A researcher researching diabetes medication, for instance, might record how many times a research participant missed the medication but not the details of what happened during a participant's day to cause him to forget to take the diabetes medication.
Demetrius Sewell is an experienced journalist who, since , has been a contributing writer to such websites as Internet Brands and print publications such as "Cinci Pulse. Typically, if you are able to achieve statistical significance with a smaller sample size, the effect size is fairly substantial.
It is important to take both statistical significance and effect size into account when interpreting your data. Data from qualitative studies describes the qualities or characteristics of something.
You cannot easily reduce these descriptions to numbers—as you can the findings from quantitative research; though you can achieve this through an encoding process. Qualitative research studies can provide you with details about human behavior, emotion, and personality characteristics that quantitative studies cannot match. While quantitative research requires the standardization of data collection to allow statistical comparison, qualitative research requires flexibility, allowing you to respond to user data as it emerges during a session.
Thus, qualitative research usually takes the form of either some form of naturalistic observation such as ethnography or structured interviews. In this case, a researcher must observe and document behaviors, opinions, patterns, needs, pain points, and other types of information without yet fully understanding what data will be meaningful.
Following data collection, rather than performing a statistical analysis, researchers look for trends in the data. When it comes to identifying trends, researchers look for statements that are identical across different research participants. The rule of thumb is that hearing a statement from just one participant is an anecdote; from two, a coincidence; and hearing it from three makes it a trend. The trends that you identify can then guide product development, business decisions, and marketing strategies.
Because you cannot subject these trends to statistical analysis, you cannot validate trends by calculating a p-value or an effect size—as you could validate quantitative data—so you must employ them with care. Plus, you should continually verify such data through an ongoing qualitative research program. With enough time and budget, you can engage in an activity called behavioral coding , which involves assigning numeric identifiers to qualitative behavior, thus transforming them into quantitative data that you can then subject to statistical analysis.
In addition to the analyses we described earlier, behavioral coding lets you perform a variety of additional analyses such as lag sequential analysis , a statistical test that identifies sequences of behavior—for example, those for Web site navigation or task workflows.?
However, applying behavioral coding to your observations is extremely time consuming and expensive. Plus, typically, only very highly trained researchers are qualified to encode behavior. Thus, this approach tends to be cost prohibitive. Additionally, because it is not possible to automate qualitative-data collection as effectively as you can automate quantitative-data collection, it is usually extremely time consuming and expensive to gather large amounts of data, as would be typical for quantitative research studies.
As a result, qualitative research tends to have less statistical power than quantitative research when it comes to discovering and verifying trends. While quantitative and qualitative research approaches each have their strengths and weaknesses, they can be extremely effective in combination with one another. You can use qualitative research to identify the factors that affect the areas under investigation, then use that information to devise quantitative research that assesses how these factors would affect user preferences.
To continue our earlier example regarding display preferences: An example of a qualitative trend might be that younger users prefer autostereoscopic displays only on mobile devices, while older users prefer traditional displays on all devices. You may have discovered this by asking an open-ended, qualitative question along these lines: In a subsequent quantitative study, you could address these factors through a series of questions such as: An automated system assigns a numeric value to whatever option a participant chooses, allowing a researcher to quickly gather and analyze large amounts of data.
When setting out to perform user research—whether performing the research yourself or assigning it to an employee or a consultant—it is important to understand the different applications of these two approaches to research. This understanding can help you to choose the appropriate research approach yourself, understand why a researcher has chosen a particular approach, or communicate with researchers or stakeholders about a research approach and your overarching research strategy.
In what other ways do you use and combine qualitative and quantitative research? The quantitative approach is so vital, even in our daily lives, because in most, if not all things we do in life, we measure to see how much there is of something. Quantitative method is part of our daily life, even from birth, data are constantly being collected, assessed, and re-assessed as we grow. I also support the quantitative data because it is much used and almost whatever we do involves it.
Both quantitative and qualitative research are important on their own. It depends on the situation where a researcher conducts a particular research, or he can go for the mixed method, too. For now, I am in need of sampling and non-sampling errors. Please help me understand its applications and the ways that can be checked? Types of sampling and all related information on this chapter.
Quantitative data provides the facts, but facts about people are just another construct of our society. Business understands that neither method should be relied upon exclusively, which is why they use both.
Anyone who thinks this is a competition between the two methods to somehow win out needs to read the article again. I also think that the quantitative approach is more important than the qualitative approach because we use it more and more in our life time. I would suggest using both quantitative and qualitative. Both are strong ways of getting information and hearing the views and suggestions of others. It would be wiser to go for a mixed research method.
This quantitative approach is the approach used to show the transparency that at the end shows the democracy in the Great lakes countries. Both methods are useful in real life situations. Quantitative research requires high levels of statistical understanding to enable the measurements of descriptive and inferential statistics to be computed and interpreted, whereas qualitative methods are critical to identifying gaps in underserved areas in the society.
More significantly, the use of a combination of the two is perfect. I am more confused when a particular method is considered superior over the other. I am more at ease looking at all three methods as situational—in that, some decision making requires the use of a quantitative, qualitative, or mixed method to accomplish my goals.
I think both qualitative and quantitative are good to go by, because the demerits of one are settled by the merits of the other. The lapses that one has are covered by the other, so I think, for better findings and more accurate results, a mixed method answers it all. Good article, provides a good general overview.
As a marketing-research consultant I want to stress that qualitative research helps you much more to collect insights for user stories—if you do SCRUM—get the reasons why that make you differ and not differ from competitors and that would allow you to positively stand out in the market.
I love the stats, measurements. Yet my clients get great stuff out of qual that quant could never deliver because it is tool for specific purposes—as qual is. If you have both in your toolbox and know how to handle them, you get a better product. Use them and use them wisely, know the strengths and weaknesses of both—or get someone who does—because your competitor might just do it right now.
Strengths and limitations. In qualitative research there is less emphasis on counting numbers of people who think or behave in certain ways and more emphasis on explaining why people think and behave in certain ways. Participants in qualitative studies often involve smaller numbers of tools include and utilizes open-ended questionnaires.

Strengths and Weaknesses of Quantitative and Qualitative Research. Insights from Research Qualitative research studies can provide you with details about human behavior, emotion, and personality characteristics that quantitative studies cannot match. While quantitative and qualitative research approaches each have their strengths and. Qualitative research displays its own strengths however, this is also associated with some disadvantages and these include the following: • The quality of research is heavily dependent on the skills of the researcher and can be easily influenced by personal idiosyncrasies and biases of .
