This chapter outlines an overview of the research approach adopted in the study as well as the research methodology and the practical approach adopted to achieve the set objectives of the study. In addition, it also highlights the data collection methods, ethical considerations, and data analysis. Case studies will be used as a research strategy as they are distinguished by their ability to investigate a phenomenon which, in this case, will be the upgrading heritage buildings through sustainable designs and construction. The chapter also rationalizes the sampling approaches and the research methods used for collecting the data in the case studies. To achieve the objectives, data for this study will be collected using two qualitative research methods: document analysis and semi-structured interviews which were used to give a scholarly definition of the term “sustainable adaptation to heritage sites and buildings” which is part of the objectives. The chapter also looks at the qualitative analysis techniques which will be used to analyze the data.
3.2 Research approach
The difference between qualitative and quantitative research is basically a methodological issue and the researcher’s decision to choose a specific research approach should be based on its suitability to answer the established research questions (Bryman, 1992). A qualitative approach according to (Creswell, 2003) should be a logical subjective approach and should be able to describe experiences and
According to Yin (2003), there are two types of research approach. This includes quantitative research approach and qualitative research approach. A quantitative research emphasizes on transforming the data to numbers, quantities and statistics to formulate facts and to uncover patterns in a research. It addresses research purposes through empirical analysis that involve numerical measurement, the relationship between variables and analysis approaches (Zikmund et al., 2010). The sample size being investigated is typically large (Anderson, 2006). Quantitative research mainly uses questionnaires, surveys and other equipment to collect numerical or measurable data (Anderson, 2006). On the other hand, a qualitative research typically emphasizes words more than numbers
Research, no matter what field, is often conducted and analysed in accordance with two basic approaches: quantitative and qualitative. The quantitative approach aims to test a hypothesis and examine the relationship through generating numerical data or other information that is than converted into numbers, whereas the qualitative approach is more exploratory, aiming to gain a deeper understanding of the research subject. Through breaking down and examining the key features in each of these approaches it is evident that although they both begin with a problem the researcher aims to understand they fundamentally differ. The table below shows side by side comparisons, highlighting the differences that can be used to differentiate these approaches, described broadly across three main categories.
This paper primarily concerns qualitative research, but we were asked to compare both qualitative and quantitative methods. During comparison, there are many noted differences in both study designs, but not many similarities. Qualitative research uses a subjective approach with a large sample population. It collects non-statistical data, using an unstructured or semi-structured technique (Nieswiadomy & Bailey, 2018). Quantitative research uses an objective approach and large, random, sampling to ask opinions in a structured way. The findings of quantitative studies are conclusive and used to recommend a final course of action (Nieswiadomy & Bailey, 2018). While it is hard to see similarities between the two, both methods aim to find a solution to a problem or question, the researcher doing the study may affect the outcome and an analysis of the collected data must be done (Souza, 2017). What many don’t realize is the connection amongst the two. You can say, both types of research build upon one another, meaning quantitative studies can quantify results found in qualitative research (Souza, 2017).
Qualitative research is subjective data and is often used in the social sciences (Sarantakos 2013, p. 48). Qualitative research is devoted to gathering facts, this can be completed through personal experiences, behaviours, and observations (Sarantakos 2013, p. 46). The purpose of qualitative research is to gather an in depth understanding of human behaviour and the explanations for the behaviour (Martijn & Sharpe 2006, p. 1). An issue with only using a qualitative method is efficacy, qualitative studies cannot address relationships between variables with the degree of accuracy that is required to establish social trends (Sarantakos 2013, p. 46).
The continued academic tension between qualitative and quantitative inquiry has continued unabated. Scholarship since the 1980s, to redefine both paradigms, attempt to bring balance and importance of the respective contribution of both research processes. This has resulted in an interesting shift for “ensuring structure, process and rigor” from the investigator’s actions during the course of the research, to the reader of the qualitative inquiry. The emphasis on Quantitative strategies implemented during the research process has been replaced by truth value, applicability,
For quite a while there has been some discussion around which method of distinctions between Qualitative research and quantitative research. This has been fired in later years with some thinking that a combination of the two is best practice especially in social
Researchers are sometimes using Quantitative and Qualitative research methodologies interchangeably, or all three of the methodologies including the mixed approach, Creswell (2009). However, the most distinctive differences between the two is the application used, or the design, using words for qualitative analysis, and
It is common for researchers to compare qualitative and quantitative research methods. Quantitative methods originate from positivist and post- positivist research paradigms. Also, the methods objectively examine statistical data to determine cause and affect and often use generalizable data. There are various methods used in quantitative research such as surveys,
Qualitative research uses data obtained through methods such face- to- face interviews, observations, and focus groups. Data is analyzed by looking for trends and patterns. Quantitative research use numerical and statics to process the answer specific questions. Statistics used to support assessment of research. Analysis techniques are used to report are affected by the questions addressed and type of information that is expected in the research discoveries (Wakoff, 2007).
Qualitative data is not numerical and is more likely to take the form of observations or interviews. Obviously, it is very difficult to perform any statistical analysis on this kind of data. A further problem is that another researcher cannot replicate this data and therefore it is difficult to check the validity of what has been written. Researchers using this kind of data must be careful to avoid subjectivity, that is, they must avoid letting their personal beliefs or preferences affect the way they record and interpret the data. The advantage of this form of data collection is that it allows the researcher to answer open-ended questions; consequently, it is more flexible. Qualitative data also provides opportunities to explain the context of an observation and can therefore present a fuller picture (OU, 2001).
The more ‘extreme’ positions in the debate between qualitative versus quantitative research state that qualitative research is “unscientific, anecdotal, and saturated by the opinions of the researcher”, whereas the latter is “not representative of human behaviour” (Natasi & Schensul, 2005).
In particular, qualitative researchers tend to focus more on the social-constructed reality and the contextual influence, interaction and constraints between the researcher(s) and the participants. They are interested in finding answers to questions that focus on the “social construction of experience and how meaning is created” (Cooper & White, 2012, p. 15). However, quantitative researchers “emphasize measurement and analysis, and focus on product rather than process” (Cooper & White, 2012, p. 15). Quantitative researchers perceive reality as observable and external so that they are interested in conducting research which is based on measurement or calculation. Therefore, it is the ontological and epistemological beliefs that usually drive the methodological preferences, but what helps the researchers make their final decisions about research methods is the guiding research question(s). Sechrest and Sidani (1995) point out the commonality that both methodologies “describe their data, construct explanatory arguments form their data, and speculate about why the outcomes they observed happened as they did (p. 78)”. Both research methodologies need to address issues of either validity or credibility, make the data unbiased and the research design as rigorous as possible.
Both of approaches have pros and cons, it is difficult to decide which research approach is appropriate for a specific research task. Excepting the selection of methods, the background information and the subjective consciousness of participants are main aspects to decide the quality of a given piece of research. Researchers should seriously consider the specific situation of the research. Meanwhile, researchers should synthesize the advantages between quantitative and qualitative research so as to effectively achieve the research aim by a mixed methodology.
In doing the research, the methodology must be appropriate so that the analysis findings could reach the objective. Research methodology proposed one procedure in order way to be follow to answer all the questions in the research that want to be made. Quoted by Denzin and Lincoln (1994), methodology is a process that related with research objective and data. In the others word, it is early research planning that include the research scope, data collection method, data collection process and data analysis method. For Ranjit (2005), methodology is one of crucial part in research, in order to ensure the research can be done in the systematic way Overall, this chapter will discuss on the research frame and the methodologies used in order to meet the research objectives. Research process been divided into three main parts there are preliminary research part, data collection and last one data analysis.
Qualitative and Quantitative study designs both can be beneficial in research design. They both provide valuable options for researchers in the field. These techniques can either be used separately in a research study or they can be combined to achieve maximum information. This paper will define the terms qualitative and quantitative; describe the similarities and differences between each; discuss how qualitative and/or quantitative research designs or techniques could be used in the evaluation of my proposed research; and discuss why linking analysis to study design is important.
