- Primary Research
- Original data collected directly from sources β through surveys, interviews, or observations β for a specific research objective.
- Secondary Research
- Analysis of data already collected by others, such as industry reports, government statistics, or academic studies, typically at lower cost than primary research.
- Cost Per Respondent
- The total cost of a research method divided by the number of usable responses, used to compare efficiency across methods.
- Fieldwork Costs
- Direct expenses incurred during data collection β including participant incentives, interviewer fees, venue hire, and travel.
- Incidence Rate
- The percentage of the general population that qualifies for a specific research study, which directly affects recruitment cost and time.
- Panel Survey
- A survey administered to a pre-recruited group of respondents who have agreed to participate in research over time, reducing recruitment costs per study.
- Qualitative Research
- Research that collects non-numerical data β opinions, motivations, and behaviours β through methods such as focus groups or in-depth interviews.
- Quantitative Research
- Research that collects numerical data at scale, typically through structured surveys, to measure frequency, preference, or statistical significance.
- Research ROI
- The business value generated by a research investment relative to its cost, often measured by the revenue impact of decisions informed by the findings.
- Blended Research Design
- A study that combines two or more methods β for example, qualitative interviews followed by a quantitative survey β to balance depth with statistical validity.
- Sampling Cost
- The expense of recruiting a representative or targeted group of participants, including screening, incentives, and panel access fees.
