5.1 Research Terminology
Nicholas Walliman, in his handbook Research Methods: The Basics, defines research methods as “the tools and techniques for doing research.”[1] These techniques include collecting, sorting, and analyzing the information and data you find. The better the tools and more comprehensive the techniques you employ, the more effective your research will be. By extension, the more effective your research is, the more credible and persuasive your argument will be.
Here are some basic terms and definitions you should be familiar with:
Research: the systematic process of finding out more about something than you already know, ideally so that you can prove a hypothesis, produce new knowledge and understanding, and make evidence-based decisions
Research Methods: techniques of collecting, sorting, and analyzing information/data
Data: bits of information.
Research Sources
The typical kinds of research sources you will use can be grouped into three broad categories:
- Primary Sources: research you might conduct yourself in lab experiments and product testing, through surveys, observations, measurements, interviews, site visits, prototype testing, beta testing, etc. These can also include published statistical data, historical records, legal documents, firsthand historical accounts, and original creative works.
- Secondary Sources: written sources that discuss, analyze, and interpret primary data, such as published research and studies, reviews of these studies, meta-analyses, and formal critiques.
- Tertiary Sources: reference sources such as dictionaries, encyclopedias, and handbooks that provide a consolidation of primary and secondary information. They are useful to gain a general understanding of your topic and major concepts, lines of inquiry, or schools of thought in the field.
Categories of Data
Data can be categorized in several ways:
Primary data
Primary data are data that have been directly observed, experienced and recorded close to the event. This is data that you might create yourself by
- Measurement: collecting numbers indicating amounts (temperature, size, etc.)
- Observation: with your own senses or with instruments (camera, microscope)
- Interrogation: conducting interviews, focus groups, surveys, polls, or questionnaires
- Participation: experience of doing or seeing something (visit the site, tour the facility, manipulate models or simulations, Beta test, etc.)
Note: primary research done in an academic setting that includes gathering information from human subjects requires strict protocols and will likely require ethics approval. Ask your instructor for guidance and see chapter 5.4 Human Research Ethics.
Secondary data
Secondary data comes from sources that record, analyze, and interpret primary data. It is critical to evaluate the credibility of these sources. You might find such data in
- Academic research: refereed academic studies published in academic journals
- Print sources: books, trade magazines, newspapers, popular media, etc.
- Online research: popular media sources, industry websites, government websites, non-profit organizations
- Non-written Material: TV, radio, film, such as documentaries, news, podcasts, etc.
- Professional Documents: annual reports, production records, committee reports, survey results, etc.
Quantitative data
Quantitative data uses numbers to describe information that can be measured quantitatively. This data is used to measure, make comparisons, examine relationships, test hypotheses, explain, predict, or even control.
Qualitative data
Uses words to record and describe the data collected; often describes people’s feelings, judgments, emotions, customs, and beliefs that can only be expressed in descriptive words, not in numbers. This includes “anecdotal data” or personal experiences.

- Drag the words (Qualitative Quantitative) into the correct boxes.
- data uses numbers to describe information that can be measured, for example, statistics.
- data uses words to record and describe the data collected.
- What type of research source is this: A chemistry experiment that you conducted?
- Secondary
- Tertiary
- Primary
- Fill in the missing words from this list: primary, secondary, tertiary
- sources are those that discuss, analyze, or interpret primary data.

- An academic article published in the British Medical Journal is what type of source?
- Secondary
- Tertiary

- Match the words (Research Methods, Data, Research) with the correct definition.
- Bits of information.
- Techniques of collecting, sorting, and analyzing information and data.
- The systematic process of finding out more about something than you already know. This is done to prove a hypothesis, produce new knowledge, and make evidence-based decisions.
Research Methods
Research methods are often categorized as quantitative, qualitative or “mixed method.” Some projects, like a science, require the use of the scientific method of inquiry, observation, quantitative data collection, analysis and conclusions to test a hypothesis. Other kinds of projects take a more deductive approach and gather both quantitative and qualitative evidence to support a position or recommendation. The research methods you choose will be determined by the goals and scope of your project, and by your intended audience’s expectations. More specific methodologies, such as ways to structure the analysis of your data, include the following:
- Cost/benefit Analysis: determines how much something will cost vs what measurable benefits it will create
- Life-cycle Analysis: determines overall sustainability of a product or process, from manufacturing, through lifetime use, to disposal (you can also perform comparative life-cycle analyses, or specific life cycle stage analysis)
- Comparative Analysis: compares two or more options to determine which is the “best” solution (given specific problem criteria such as goals, objectives, and constraints)
- Process Analysis: studies each aspect of a process to determine if all parts and steps work efficiently together to create the desired outcome.
- Sustainability Analysis: uses concepts such as the “triple bottom line” or “three pillars of sustainability” to analyze whether a product or process is environmentally, economically, and socially sustainable.
Researching with Integrity
In all cases, the way you collect, analyze, and use data must be ethical and consistent with professional standards of honesty and integrity. Lapses in integrity can not only lead to poor quality reports in an academic context (poor grades and academic dishonesty penalties), but in the workplace, these lapses can also lead to lawsuits, loss of job, and even criminal charges. Some examples of these lapses include
- Fabricating your own data (making it up to suit your purpose)
- Ignoring data that disproves or contradicts your ideas
- Misrepresenting someone else’s data or ideas
- Using data or ideas from another source without acknowledgment or citation of the source.
Failing to cite quoted, paraphrased or summarized sources properly is one of the most common lapses in academic integrity, which is why your previous academic writing class spent considerable time and effort to give you a sophisticated understanding of how and why to avoid plagiarizing, as well as the consequences of doing so. If you would like to review this information, see Appendix C: Integrating Source Evidence into Your Writing, and consult the University of Victoria Calendar entry on Academic Integrity.
