CEAC Research Methods & Evidence-Based Practice 3

Question 1

Which of the following best describes a prospective cohort study in the context of accessibility research?

Accepted Answer

Participants are followed forward in time to observe outcomes after exposure

Answer

Prospective cohort studies follow participants forward from exposure to outcome, allowing observation of incidence and temporal relationships.

Question 2

What does a high inter-rater reliability score indicate in an accessibility assessment tool?

Accepted Answer

Different evaluators using the tool produce consistent results

Answer

Inter-rater reliability measures the degree to which different assessors produce the same scores using the same tool.

Question 3

When a research study reports a 95% confidence interval that does not include zero for an accessibility intervention effect, this means:

Accepted Answer

The result is statistically significant at the 0.05 level

Answer

A 95% CI excluding zero indicates the effect is statistically significant at alpha = 0.05, meaning the null hypothesis of no effect is rejected.

Question 4

A consultant wants to survey wheelchair users about barriers in a city's transit system. Which sampling method would yield the most representative results?

Accepted Answer

Stratified random sampling by transit zone and disability type

Answer

Stratified random sampling ensures proportional representation across subgroups, reducing bias and improving generalizability.

Question 5

Which hierarchy of evidence places expert opinion at which level?

Accepted Answer

Lowest level because it is most prone to bias

Answer

Evidence hierarchies place expert opinion at the lowest level due to susceptibility to bias and lack of systematic methodology.
