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.

Data collection is based on participants' meanings rather than a more objective collection of statistics. Qualitative research often involves cross-case comparisons. 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.

Describe the uses of quantitative research design. Provide examples of when quantitative research methodology should be used. Discuss the strengths and weaknesses of quantitative research. The data collected is numeric, allowing for collection of data from a large sample size.

Statistical analysis allows for greater objectivity when reviewing results and therefore, results are independent of the researcher. Numerical results can be displayed in graphs, charts, tables and other formats that allow for better interpretation. Data analysis is less time-consuming and can often be done using statistical software.

Results can be generalized if the data are based on random samples and the sample size was sufficient. Data collection methods can be relatively quick, depending on the type of data being collected. Numerical quantitative data may be viewed as more credible and reliable, especially to policy makers, decision makers, and administrators.

How often do college students between the ages of access Facebook? What is the difference in the number of calories consumed between male and female high school students? What percentage of married couples seek couples counseling?

How many organized sports activities has the average 10 year old child competed in? Planning, conducting, and evaluating quantitative. Qualitative, quantitative, and mixed methods approaches.

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. However, I prefer qualitative research for the reasons that studies are cheaper to embark on and the means of data collection and analysis are less stressful. I think qualitative research is best because it involves face-to-face conversation with the respondents.

It gives true and reliable data as compared to quantitative research, because those researchers obtain data only from a given source and quantify it. I need the advantages and disadvantages of using the T-test data collection method for the United States Parcel Service about their competition. I am not sure which is better for this, t-test or not, since t-test deals in small samples whereas UPS is global.

I still have to know some disadvantages and advantages though. I think a qualitative approach is more imperative. It provides greater richness and more detailed information about a smaller number of people. I think qualitative research is easier to make meaning from, as it simplifies the phenomena by giving details on the issues.

I beg to differ from most comments. I support qualitative research because of the quality of its results. This concept of quantitative research is good. You can as well make a video of this and place it on Netflix for people to watch. Demetrius truly believes in the power of user research—when it is done well.

Quantitative Studies Quantitative studies provide data that can be expressed in numbers—thus, their name. Qualitative Studies Data from qualitative studies describes the qualities or characteristics of something.

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. The most significant strength is the increased ability to generalize quantitative results to the greater population. In fact, such power increases dramatically as we move left-to-right from quantitative descriptive studies, to correlations, and, finally, into experiments.
