Section III. Choice of Research Method: Quantitative, Qualitative or Mixed?
The selection of data analysis techniques to deal with research questions or hypotheses and the techniques chosen for the data collection is informed and guided by what we call the research method. Hence, research method is a procedure, and also the analytical techniques to be chosen and the methods to be chosen will also be dictated by the choices of the methodologies made and by the theoretical framework (Sumner and Tribe, 2008).
Research methods for knowledge claim and strategies is of three types: quantitative, qualitative, and mixed methods. In quantitative method, a positivist claims is used as a tool for the researcher to investigate primarily for knowledge. …show more content…
Among it, the most important are that the results of the study can be generalized to the population where the data is obtained through sampling of individuals to make the results as representative as possible to the target population. It also helps to understand the cost and benefit of interventions and the magnitude and distribution of impacts of some intended programs, and provides first-hand information to analyze on how structural factors that affect different inequalities are produced. The extraneous variables can be controlled so that its effect on erroneous interpretation of validity can be removed. As each method has its own strength, so does their limitations. Some of the usually pronounced weaknesses of the quantitative method are related to difficulties related to sensitive issues like income or sexual practice, and since many groups such as the minorities are difficult to reach, information obtained may be incomplete and/or inaccurate. Indeed, the method is expensive and time consuming. And the method is also inflexible since after the study begins, the instruments cannot be modified (Bamberger, 2000; Rao and Woolcock, 2003; Sumner and Tribe

Paul, Thanks you so much. I will spend today and part of tomorrow to rewrite the abstract to make more stronger substantial contribution to theory (Descriptive Theory) and practice of research ( Mixed Method - Qualitative Driven and Quantitative Supplementary Component Cross National Comparative). I will try and phone you if that is okay. Thanks again Regards
n research methods, every researcher uses a procedure or a means of measurement to collect data. For example, three types of basic measurement collection are self-reports, observational, and physiological. Each method has their pros and cons in research. Depending on the research you are conducting these methods of measurement can either guide you to great discovery the pro, or skew your data making it unreliable the con. Observational measure is the method of measuring behaviors by directly observing subjects (Leary, M. R. (2011).
Unit Three Freakonomics Response Chapter 5 of the book Freakonomics addresses what the possible reasons that make a child do well on standardized testing. The options are, what a parent does for a child or what a parent is. The answers are somewhat surprising. They also make me feel a little better.
Health disparities; i.e. a difference in health among segments of population based on the social determinants of health have a significant impact on the individuals health status and their ability to access healthcare services. Although the overall health of the United States population has improved, large disparities in terms of health outcome and access to healthcare exist between wealthier Americans and their “poorer counterparts primarily because of differences in education, behavior, and environment. Higher incomes permit people to buy healthier food; live in safer, cleaner neighborhoods; and exercise regularly” (Longest, 2015, p8). Over the last two decades, the public health community’s attention has placed lots of emphasis on addressing the non-medical factors, such
It can also reduce substantial error and bias in a study design when the data is attempting to determine culturally different groups (Kaneshiro et. al, 2011). Furthermore, much of public health research is based on aggregated data. Therefore, it is easier to compare research to previous studies to determine if there has been an improvement in the population or assess the effectiveness of current intervention programs. In addition, aggregated data has been able to develop the best practices for asking questions to minority groups.
The current healthcare reform movement is calling for health institutions to evaluate and redesign the historical approach to healthcare in order to reduce costs and improve outcomes for the population. Unfortunately, “the health sector itself has little or no direct control over most of the underlying conditions required for health” (Braveman & Gruskin, 2003, p. 541). These underlying conditions can best be described as the social determinants of health (SDH) defined by the World Health Organization (WHO) as “the conditions in which people are born, grow, live, work [and] age,”. The Ottawa Charter (1986) further defined the prerequisites for health a bit more clearly as peace, shelter, education, food, income, a stable eco-system, sustainable
According to Creswell (2014), this would make the research approach, mixed method. Mixed method research is the combination of qualitative and quantitative research (Creswell, 2014). The researches used interviews, which would be considered qualitative. In addition, scales and indexes were used which do not allow for any explanation from participants, and would therefore be considered quantitative (Creswell,
Health statistics are important for knowing the health status of the whole population and its various segments and groups, as well as the trend in health status, the provision and distribution of healthcare services, and the impact of the provided services and programs. he success or failure of healthcare programs cannot be veriied without properly collected and interpreted health statistics. Proper allocation of resources also depends on health statistics. Researchers, presenters, and health care workers and students always need health statistics. However, it is not uncommon to ind a local article or presentation, which reports health statistics from all over the world, but fail to report local statistics from the Kingdom of Saudi Arabia (KSA).
“Quantitative research is conducted in a context of previous knowledge” (Polit & Beck, 2017, p. 54)., which could limit a researcher based off their amount of previous knowledge on the subject being studied. And the researcher collect data from a sample size of a population. The sample’s adequacy is assessed by its size and representativeness. (Polit & Beck, 2017). A small sample size could limit the validity of the
The term Research Methodology refers to a set of procedures, methods & techniques that are put together by the researchers to obtain a solution to the problems they confront during the collection of data. The researchers look for the most crucial data which is inevitable for the research. Generally there are three kinds of approaches or research methods namely Qualitative, Quantitative and Mixed. These methods are used to gather data and resolve issues that emerge during the process of data gathering. The researcher can bring forward his findings either in the form of quantitative or qualitative or mixed research methodologies only when the data is collected based on the preliminary data gathering process and the secondary data gathering process.
Mixed method approaches are commonly regarded as more robust that singular approaches, and can offset limitations associated with one approach or the other (Creswell, 2009:4). For example, quantitative researchers have a limited connection to their subjects. Conversely,
Methodology In my thesis I utilized the quantitative content analysis method. There are many definitions of this research method from different authors. Most of the definitions include similar principles. The research should be systematical, objective, quantitative and replicable.
Also, the indicators that have been used in this are limited in number. By increasing the number of indicators the accuracy of the study can be increased dramatically. When the number of indicators used for analysis is lower not only will a lot of data not get considered but also the accuracy that one requires for the study will not be achieved.
