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.

Bryan enjoys innovating user research methods that integrate communication skills, working with such companies as eBay, Kodak, Microsoft, and BAE Systems. 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. Using Quantitative and Qualitative Research Together While quantitative and qualitative research approaches each have their strengths and weaknesses, they can be extremely effective in combination with one another.
Conclusion 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. Join the Discussion Full name. Both qualitative and quantitative research are used in studies throughout many disciplines, including science and the social sciences.
Qualitative research is concerned with complete and detailed descriptions of events, whereas quantitative research creates statistical models to explain events.
Qualitative and quantitative research have several advantages and disadvantages, depending upon the researcher's aim and area of focus.
Qualitative research is useful during the early stages of a study when the researcher may be unsure of exactly what will be studied or what to focus on. This type of research does not need a strict design plan before it begins. This gives the researcher freedom to let the study unfold more naturally. Another advantage to qualitative research is the researcher gains more detailed and rich data in the form of comprehensive written descriptions or visual evidence, such as photographs.
This type of research looks at context and social meaning and how it affects individuals, which is advantageous particularly in the social sciences. The researcher of a study using qualitative research is heavily involved in the process, which gives the researcher a subjective view of the study and its participants.
Some dissertations and research studies take a mixed method approach, which incorporates qualitative and quantitative methods in different phases to obtain a broader perspective.
You may be very familiar with quantitative research from your science classes where you learned and practiced using the scientific method. A problem or question is examined by deductively forming a hypothesis derived from theory.
Controlled, objective testing and experimentation ultimately supports or rejects your hypotheses. Each step is standardized to reduce bias when collecting and analyzing data. A big advantage of this approach is that the results are valid, reliable and generalizable to a larger population. Quantitative research is advantageous for studies that involve numbers, such as measuring achievement gaps between different groups of students or assessing the effectiveness of a new blood pressure medication.
While quantitative research methods work well in the laboratory under tightly controlled conditions, measuring phenomena like human behavior in natural settings is trickier. Survey instruments are vulnerable to errors such as mistakes in measurement and flawed sampling techniques. Another disadvantage is that quantitative research involves numbers, but some topics are too difficult to quantify in numbers.
For example, constructing an effective survey with closed-ended questions about how people fall in love would be difficult. Qualitative research is often used to conduct social and behavioral studies because human interactions are more complex than molecular reactions in a beaker.
Subjectivity, nonrandom sampling and small sample size distinguishes qualitative research from quantitative research. A big advantage of qualitative research is the ability to deeply probe and obtain rich descriptive data about social phenomena through structured interviews, cultural immersion, case studies and observation, for instance.
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 researchers.
Knowing the advantages and disadvantages of quantitative and qualitative methods will help you make a better decision. Both methods are quite useful depending on the type of study. Some dissertations and research studies take a mixed method approach, which incorporates qualitative and quantitative methods in different phases to obtain a .
This study, therefore, aims to discuss the advantages and disadvantages of using qualitative and quantitative research approaches and methods in language testing and assessment research. There is a focus on ethical considerations too. A truly important point in the comparison between quantitative research and qualitative research is that the subjective participation of the researcher -- that is one of the most resilient objections regarding qualitative research -- takes place in quantitative .
Qualitative and quantitative research have several advantages and disadvantages, depending upon the researcher's aim and area of focus. Advantages of qualitative research Qualitative research is useful during the early stages of a study when the researcher may be unsure of exactly what will be studied or what to focus on. Advantages and Disadvantages of Quantitative research Quantitative data is statistics driven and can provide a lot of information. One of the advantages of this type of research is that it is easier to compile the data onto a chart or graph because of the numbers that are made available (Word press, ).
