What Is Quantitative Research?

The importance of Quantitative and Qualitative Research in Customer Experience Measurements

❶Thus, this approach tends to be cost prohibitive. Measurement is often regarded as being only a means by which observations are expressed numerically in order to investigate causal relations or associations.

Why Do You Use a Questionnaire to Collect Data?
Qualitative Studies

Although time consuming to conduct, qualitative research tends to offer forth a wealth of varied information on a small case or set of cases over a broad set of data. The breadth Becker refers to means being open to the multiple causes of every event.

Well done qualitative research is limited in its scope, but very rich in depth. It can help us see how many different causes and actions lead to specific outcomes. Likewise, a qualitative approach can point out the limitations of our own theories and categories. Qualitative researchers are also often acutely aware of how their own preconceptions and presence may affect a situation.

This attention can, I think, lead to better research that helps clarify our vision. So what are the advantages of such an approach? Qualitative research focuses attention on the contingent nature of social reality. Institutions, technologies, and broad social forces matter, but their effects are always specific to a particular context. The case-study nature of qualitative research allows a focus on how things went down, how general forces and individual wills played out in a specific situation.

This impulse is incredibly relevant for development work. The video Andrew posted about several failed development technologies in some ways follows this point—we need to pay attention to affects in particular contexts and under real human conditions.

In practice this is always a lot sloppier, imperfect, and ethically complicated. Caveats in place, what I will show you over my next couple of posts are some examples of well conducted qualitative research that can help shape the way we think about development.

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. Both methods play an equal role, especially in research, and may also influence each other. This will depend on time and the necessity for each method.

A significance level set to 0. That is, one might observe statistical significance, regardless of sample size, but this may be a false positive—that is, the effect occurs by chance or due to the co-occurrence of other factors. In general, one should be cautious about making inferences based on results drawn from a small sample.

It must be remembered that the two methods are not competing. They complement each other. Employing both techniques is the surest way to get your research budget well spent. Minini, Faith Harrison—In my opinion, all three research approaches—quantitative, qualitative, and mixed methods—are very useful in informing UX practice.
