Appropriate research is that which has employs different methods of research to gather information concerning a specific phenomenon. To come up with credible findings for both qualitative and quantitative studies, descriptive, analytic and evaluative research should be employed by a researcher.

Descriptive Research

The research method is explanatory. It puts more emphasis on identifying individuals who are vulnerable within a larger subset of the study population so that actions could be taken to improve their welfare (Burkholder & Nash, 2013, p.4). In the study of the homeless individuals, the method will be used to identify the most vulnerable group within the homeless individuals

Analytic Research

The technique focuses on studying factors that contribute to the vulnerability of the individuals identified in the descriptive study. It is also useful in developing mechanisms to address the risk factors Burkholder & Nash 2013, p.4). In the study of the homeless individuals, analytical research will be used to identify the social, economic and political risk factors risk that increase the vulnerability of identified individuals and develop programs to minimize the vulnerability of the group.

Evaluative Research

This study aids in establishing the success of the programs aimed at reducing the vulnerability of identified groups. The evaluative method will be applied in the study of the homeless individuals to assess whether the educative and empowerment programs initiated have improved their welfare.

Research Issues

Each of the three research methods requires a researcher to uphold the legal, accreditation and ethical issues while researching the identified populations. The researcher is expected to obtain approval from legal entities associated with the study (Jervis & Drake, 2014, p.235). The institutions in which the researcher is affiliated must be accredited for research activities. Also, the researcher must uphold ethical aspects such as privacy of the respondents’ information, avoidance of biasness, getting consent from the respondents as well as the respect of the respondents’ culture.

Challenges

A researcher requires a longer time to carry out a descriptive study. Analytical research requires the researcher to have an in-depth knowledge of the culture of the people which is sometimes difficult to acquire (Jervis & Drake, 2014, p.239). Lastly, evaluative research requires the researcher to spend longer times with the study population to identify the impacts of the programs meant to address their issues.
