Which of the following best describes a prospective cohort study in the context of accessibility research?
Answer: Participants are followed forward in time to observe outcomes after exposure
Prospective cohort studies follow participants forward from exposure to outcome, allowing observation of incidence and temporal relationships.
What does a high inter-rater reliability score indicate in an accessibility assessment tool?
Answer: Different evaluators using the tool produce consistent results
Inter-rater reliability measures the degree to which different assessors produce the same scores using the same tool.
When a research study reports a 95% confidence interval that does not include zero for an accessibility intervention effect, this means:
Answer: The result is statistically significant at the 0.05 level
A 95% CI excluding zero indicates the effect is statistically significant at alpha = 0.05, meaning the null hypothesis of no effect is rejected.
A consultant wants to survey wheelchair users about barriers in a city's transit system. Which sampling method would yield the most representative results?
Answer: Stratified random sampling by transit zone and disability type
Stratified random sampling ensures proportional representation across subgroups, reducing bias and improving generalizability.
Which hierarchy of evidence places expert opinion at which level?
Answer: Lowest level because it is most prone to bias
Evidence hierarchies place expert opinion at the lowest level due to susceptibility to bias and lack of systematic methodology.
A CEAC professional is evaluating whether a new bathroom modification protocol reduces fall risk. Which outcome measure would be most objective?
Answer: Prospectively recorded fall incident logs
Prospectively recorded fall incident logs provide objective, verifiable data not subject to recall bias or subjective interpretation.
In a mixed-methods accessibility study, when would qualitative data be most valuable?
Answer: To explain the 'why' behind quantitative findings
Qualitative data provides contextual understanding and explores the reasons, experiences, and meanings behind quantitative results.
