Research entail qualitative and quantitative methods, qualitative and quantitative methods each with different advantages and disadvantages. Qualitative research has various advantages including ability to access people’s experiences due to the use of opinions and claims by the research interviewees. The other advantages of qualitative research are that it is less expensive due to utilization of small samples and that it does not require strict plan to carry out (Christos & Katsirikou, 2010). The first disadvantage of qualitative research is that it does not allow generalization of results to the entire population due to the use data in terms of behavior, feelings, and thoughts of the sample. Other disadvantages are that it does not allow the collection of statistical research data, time consuming and that it introduces research bias due to subjectivity.
Benefits of quantitative research are that it permits the measurement and analysis of data, which increases objectivity in research (Christos & Katsirikou, 2010). Other advantages of quantitative data are that it allows the researcher to test hypothesis, allows for generalization of conclusions to the population, departs from organization objectives, and can be inconsistent. The disadvantages of statistical research is that it uses large samples, hence an expensive research method. Other quantitative research advantages are that the study is in an artificial environment not the natural setting and that it does not allow flexibility of data (Christos & Katsirikou, 2010).
Both qualitative and quantitative research methods aids in better understanding of the variables in the study.
