❶Besides, the value of any qualitative research is to provide valid results which are only possible after extensive research.

Moreover, it stimulates individual experiences by creating pictures to express feelings and emotions. It also provides detail information in regards to data analysis, which provide unbiased and reliable information.

By recording feelings, behaviors and attitudes, qualitative research is able to gather all the information to support the findings. Besides its many benefits, qualitative research also has its share of disadvantages as well.

It is not possible to make systematic assessments when individuals give differing reactions that are subjective. Benefits of Qualitative Research Qualitative research simply represents methods or principles that are believed to affect science of human world. Qualitative studies often take more time to complete due to the pain staking nature of gathering and analyzing field notes, transcribing interviews, identifying themes and studying photographs, for instance.

Studies are not easily replicable or generalizable to the general population. Lacking rigorous scientific controls and numerical data, qualitative findings may be dismissed by some researchers as anecdotal information. A mixed method approach capitalizes on the advantages of the quantitative and qualitative methods while offsetting the drawbacks of each. For instance, a principal interested in building rapport with parents of school children might undertake a mixed method study.

First, the principal would send out a school climate survey to parents asking them to rate their satisfaction with the school and quality of instruction. Focus groups could then be organized to gather qualitative information from parents to better understand their concerns.

Because the data is in a numeric form, we can apply statistical tests in making statements about the data. These include descriptive statistics like the mean, median, and standard deviation, but can also include inferential statistics like t-tests, ANOVAs, or multiple regression correlations MRC.

Statistical analysis lets us derive important facts from research data, including preference trends, differences between groups, and demographics. Multivariate statistics like the MRC or stepwise correlation regression break the data down even further and determine what factors—such as variances in preferences—we can attribute to differences between specific groups such as age groups.

Quantitative studies often employ automated means of collecting data such as surveys, but we can also use other static methods—for example, examining preferences through two-alternative, forced-choice studies or examining error rates and time on task using competitive benchmarks. Some respondents may feel that President Obama is too liberal, while others may feel that he is too conservative in his actions, but without the necessary data, there is no way to tell.

In a product-development environment, this data deficiency can lead to critical errors in the design of a product. Additionally, only someone with a firm grasp of how they should use and interpret quantitative statistics should conduct such a study.

For most tests, there is an overreliance on the p-value and sample size. The p-value is a statistic that indicates the likelihood that research findings were the result of chance.

If a p-value is less than. If your study is underpowered because of its having two small a sample size, you may fail to achieve statistical significance—even if the finding is accurate. The reality is not too far off. However, it is possible to increase sample sizes to a point where statistical significance is barely meaningful. In such a situation, it is important to look at the effect size — a statistic that tells you how strongly your variables effect the variance.

Basically, statistical significance tells you whether your findings are real, while effect size tells you how much they matter. 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.
