Among the benefits of quantitative research is that it lets scientists conduct broad research with many subjects, which produces more accurate results. Drawbacks include relatively rigid methods and lack of behavioral analysis on subjects. Quantitative research is a useful tool for measuring and analyzing large amounts of data. It is ideal for understanding the relationship between a dependent and an independent variable.
Researchers often use quantitative research to test their hypotheses in an experiment, to carry out statistical analysis and to conduct large-scale research on the general population, such as collecting data for a consensus. People use quantitative research for specific purposes, including getting answers to questions that require numbers and frequency.
Researchers might take surveys of citizens, for example, to determine the presence of certain behaviors and attitudes in relation to the broader public. To determine whether or not these trends exist at the group level, researchers must use a large sample size to compare results to other groups in the population.
To carry out their studies, researchers generally survey at least several hundred people. They might also give people questionnaires to complete. Common uses for quantitative research includes studying the behaviors of a certain group within a community, looking for behavioral patterns in a certain segment population, and finding out what percentage of the population remembers and understands certain messages.
Benefits of Quantitative Research In addition to providing researchers with a fast and efficient way of studying a large sample size, quantitative research yields objective results. Researchers gather objective, numerical data through quantitative research that is difficult to interpret in multiple ways. Because the data is straightforward, the results can be easily compared with other data.
Another advantage of quantitative data is that it uses statistical methods of collection. This allows researchers to understand and interpret large amounts of inherent characteristics in the data. Lastly, the data that researchers collect through quantitative research can be put to future use by creating campaigns and programs targeted to the studied group.
Quantitative research results can be disseminated anonymously, which makes participants more willing to join in the study and makes it easier to evaluate sensitive topics. 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.
Examples include ethnography, narratives and grounded theory. 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. Mary Dowd is a dean of students who holds a doctorate in educational leadership from Minnesota State Mankato.

Selecting the best research method allows you to successfully answer a research question or test a hypothesis. Missteps at the onset of the research process may derail an otherwise promising study. Knowing the advantages and disadvantages of quantitative and qualitative methods will help you make a.
Benefits Of Quantitative Research 1. Summarize large information. The use of standard means in quantitative research means 3. Eliminates bias. An important reason why most researchers opt for quantitative research is 4. Finalizes results. Quantitative research is a great method to finalize results.
Quantitative research provides clear statistical data for inference and supports larger sample sizes which translates to more generalizability over the population being studied. A disadvantage is that because it is statistical based, quantitative research provides a less personal accounting of a given lived experience.

Qualitative research is a general term pertaining to investigative methodologies and techniques described as naturalistic, ethnographic, field, anthropological or observer research. This type of research gives emphasis on the value of looking on variables in their natural setting where they are commonly found. A: Quantitative methods are advantageous because they allow researchers to conduct a broad survey, which involves many subjects and generalization of findings. They also yield accurate results. On the other hand, quantitative methods are rigid and provide less detail on the motivation, attitudes and behavior of study subjects.
