Research Methods Essay -- Quantitative Method, Qualitative Method

Quantitative and Qualitative are said to be systematic in different design. Both design have to follow a process system that involved defining a principle of research. General speaking, quantitative research is thought to be objective, however qualitative research often involves a subjective element. There are differences designs in qualitative research in comparison to quantitative research. Qualitative research involves words, pictures, or objects; Quantitative involves data in the form of numbers and statistics. However, the researcher uses in-depth interviews in qualitative research to find out how the subjects view their world. In quantitative research the researcher uses precise measurement to predict hypotheses. Whereas, qualitative research the researcher changes the environment of the subject and uses these in-depth questionnaires to find differing attitudes about the world we research live in. Similarly, quantitative can be personal, such as in the periodic visits with the researchers to analysis symptoms and record data. Qualitative and Quantitative can overlap each other, for example, in the in-dept interview process in quantitative research to record data and test subjects for symptoms. They can overlap but conclusively differences such numerical data collection and statistics that will always be at odds. Qualitative and Quantitative design have many advantage and disadvantage. There are different designs that allow researches to draw different kinds of conclusions and Interpretations. For example Qualitative research can be critical. Qualitative data are extremely varied in nature. For Example, Quantitative focuses on tightly controlled variables in a structured setting to provide an explanation of la... ...earch checks reliability and validity in the form of prolonged treatment, triangulation, and persistent observation. For Example, Quantitative in Nonexperimental research involves observing and measuring things as they are. Naturalistic observation, interview, survey, case history, and psychometric scales are some of the methods used when it is not possible or unethical to manipulate an independent variable. Nonexperimental research is used to provide solutions to problems. Nonexperimental research can add to what we know by common sense because we can test our beliefs to see how true they are. Both methods also have ways of sampling. Random sampling is preferred in quantitative research. This allows the researcher to pick a representation of a larger group and the results can be generalized to the larger group. In qualitative research, sampling is not random.
