Constructon dissertation guide part 3 - Research strategy
After collating relevant material and deciding on a focus for the analysis, teh next stage is to design an appropriate research strategy, that is, the way in which the research objectives can be questioned.
Very broadly, there are two types of research strategies available – ‘quantitative’ and ‘qualitative’.
Quantitative research is an objective measure of definable factual evidence such as numbers and statistics that are capable of being analysed to determine the validity of a hypothesis.
Quantitative research can be used deductively to test a theory that can be presented in one of two ways:
- A hypothetical statement such as ‘if x then y’.
- An educated ‘guess’.
Data accumulated through the research process should help to prove or disprove the hypothesis.
Qualitative research is a more subjective measure of descriptions, views, opinions, and alternative theories. Depending on the approach taken, the research may use a smaller sample than quantitative research, but the data obtained can be more personal and in-depth. The relationship between the theory and the research is emergent or developing.
Broadly, the two categories of qualitative research are exploratory and attitudinal:
- Exploratory research is used primarily to gain a greater understanding of a particular subject. It is useful for diagnosing a situation, considering alternative ideas and discovering new ones that haven’t been previously considered. The most common method of exploratory research is interviewing, where the raw data will be the transcribed answers. Another common method is a questionnaire (usually with open-ended questions).
- Attitudinal research is used to evaluate the opinions or views of individuals in a way that is subjective. Examples are questions that ask the individual to express their level of agreement with a statement, or to rank preferences.
The main approaches to primary data collection are:
Used to gather data from a large sample size within a defined time frame. Surveys can be descriptive, asking what?, where?, when?, and so on, or analytical, establishing the relationship between attributes of the survey.
A small number of specific example analysed as a means of supporting the overall argument. Conclusions drawn will be related to the particular case studies and may not be easily generalised to the rest of the industry.
 Problem-solving / experimentation
This is a more action-based option, where certain changes are introduced/proposed and the impacts observed and analysed. This may for example involve experimentation. Particular skills, and sometimes equipment can be required for problem-solving research and so it is not always suited to the time and resource restrictions of a dissertation project.
These can be found in libraries and online, such as those conducted and published by leading institutions including RIBA, RTPI, BRE, CIOB, RIBA, CIRIA, ICE, IStructE, CIBSE and so on. See Construction industry institutes and associations for more information.
This is similar to analysing content during the literature review. With an eye on how relevant, factually accurate and reliable it is.
 Check your approach
It is very important at this stage that you discuss your approach with your supervisor to ensure it is suitable before proceeding with the actual research.
Continue to the next stage: Questionnaires and interviews.
