IFSTA Research and Development 2 — Questions and Answers
Question 1: In fire service R&D, what does the term 'validity' refer to in the context of a research instrument?
- The consistency of results across repeated measurements
- The degree to which an instrument measures what it is intended to measure (Correct answer)
- The statistical significance of the findings
- The sample size required for accurate results
Correct answer: The degree to which an instrument measures what it is intended to measure
Validity refers to whether a research instrument actually measures the concept it is designed to measure.
Question 2: Which type of research design is most appropriate when a fire service researcher wants to establish a cause-and-effect relationship between training hours and firefighter performance?
- Descriptive survey research
- Historical/archival research
- Experimental research with a control group (Correct answer)
- Case study research
Correct answer: Experimental research with a control group
Experimental research with a control group is the gold standard for establishing cause-and-effect relationships.
Question 3: What is the primary purpose of a 'literature review' in a fire service research project?
- To satisfy IRB requirements before data collection
- To identify existing knowledge gaps and contextualize the study (Correct answer)
- To replace primary data collection when time is limited
- To list all sources consulted during report writing
Correct answer: To identify existing knowledge gaps and contextualize the study
A literature review synthesizes existing research to reveal gaps and provide context for the new study.
Question 4: When conducting a needs assessment for fire department training, which data source would be considered PRIMARY data?
- Published NFPA statistics on firefighter injuries
- NIOSH Firefighter Fatality Investigation reports
- Direct surveys of current department members (Correct answer)
- Historical after-action reports from other jurisdictions
Correct answer: Direct surveys of current department members
Primary data is collected firsthand by the researcher directly from the source population.
Question 5: A fire department pilot-tests a new incident command worksheet with 10 company officers before full deployment. This process is best described as:
- Formative evaluation (Correct answer)
- Summative evaluation
- Needs analysis
- Impact assessment
Correct answer: Formative evaluation
Formative evaluation occurs during development to improve a program or tool before final implementation.
Question 6: In fire service research, what does 'triangulation' mean?
- Using geometric calculations to determine fire spread rates
- Using multiple data sources or methods to cross-validate findings (Correct answer)
- Dividing a study area into three geographic zones for sampling
- Applying three separate statistical tests to the same dataset
Correct answer: Using multiple data sources or methods to cross-validate findings
Triangulation strengthens research credibility by corroborating findings through multiple independent data sources or methods.
Question 7: Which statistical measure describes the SPREAD or dispersion of data in a fire service research dataset?
- Mean
- Median
- Mode
- Standard deviation (Correct answer)
Correct answer: Standard deviation
Standard deviation quantifies how spread out data values are around the mean.
