Quantitative Research “refers to the systematic empirical investigation of social phenomena via statistical, mathematical or computational techniques.” Quantitative research is usually categorized by descriptive research, experimental research, correlational research, and causal-comparative research. Qualitative research is used to develop and integrate mathematical models or theories to gain results. Quantitative are results of data that are in the form of numbers and statistics. While qualitative research uses word form top gain results and data. Quantitative research uses numerical data to gain and test results.
Quantitative Research generalizes results from a sample to the population of interest. The objective is to “measure the incidence of various views and opinions in a chosen sample. The sample is usually a large number of cases representing the population of interest.” Data collection can stem from surveys, questionnaires, or interviews.
Quantitative research can be used in a variety of ways to gain results. While qualitative research can offer results using an individuals opinion, quantitative research does not have any room for opinions, as results are usually required to have some numerical and statistical depth to them. I think quantitative research is great for businesses as the corporation will be able to know where they stand amongst their competition. It can also be used in instances where a part may need to be ordered and an exact number is needed to know how many of each part is being requested.
My manager uses quantitative research on a daily basis as he continues to inform us of how many prospects we have gained over the past week or month. He also listed our year to date progress and goals for the next month or year. I think this is great, as my team and I always know where we stand when it comes to the numbers specifically for what our department does. My team and I have also been given the responsibility to research the quantitative results we obtain individually for our designated Masters Degree programs. This not only helps us with learning how to obtain this information and how to use it, but also allows us the ability to track our own work and see how much we have accomplished as individuals.
While quantitative research will probably always be extremely useful for an organization, I also feel that there would be no success without it. A company must always know where they stand amongst their competitors and in their industry. However, qualitative research has just the same amount of importance as quantitative research as this type of research will provide an organization with results that are needed to help run the company for it to be successful. I think that both are needed and desired at all levels to achieve and maintain success.

Qualitative Research is defined as the method of inquiry employed in many different academic disciplines, traditionally in the social sciences, but also in market research and further contexts. Qualitative research is the study of human behavior, and why individuals may make certain decisions. Unlike quantitative research which relies specifically on numbers and statistics, qualitative research relies on the why’s and how’s of “unstructured information.”

                “Qualitative research is used to gain insight into people's attitudes, behaviors, value systems, concerns, motivations, aspirations, culture or lifestyles. It’s used to inform business decisions, policy formation, communication and research. Focus groups, in-depth interviews, content analysis, ethnography, evaluation and semiotics are among the many formal approaches that are used, but qualitative research also involves the analysis of any unstructured material, including customer feedback forms, reports or media clips.”

            The three most common methods of qualitative research are participant observation, in depth interviews, and focus groups. Qualitative research is generally more flexible than quantitative research, as qualitative research tends to offer more open ended questions, and complex inquiries for participants to answer. Responses offer greater detail and tend to be more elaborate allowing for much flexibility.

            The three most common sampling methods of qualitative research are purposive sampling, quota sampling and snowball sampling. A purposive sample is a sample selected in a deliberative and non-random fashion to achieve a certain goal. Quota sampling is a method for selecting survey participants. In quota sampling, a population is first segmented into mutually exclusive sub-groups. Then judgment is used to select the subjects or units from each segment based on a specified proportion. Snowball sampling is a non-probability sampling technique where existing study subjects recruit future subjects from among their acquaintances.

Qualitative research is extremely useful as it “expands the range of knowledge and understanding of the world beyond the researchers themselves. It often helps us see why something is the way it is, rather than just presenting a phenomenon.” The flexibility of qualitative research offers the necessary knowledge it takes for one to understand all levels of research and understanding in a specific study.
