Research Methodology Flashcards

In evidence-based design, a 'hypothesis' is best described as:

Answer: A testable prediction about the relationship between a design element and an outcome

A hypothesis is a specific, testable prediction that guides how a design intervention will affect measurable outcomes.

Which data collection method is classified as qualitative in EBD research?

Answer: Focus group interviews

Focus group interviews capture subjective experiences and opinions, making them a qualitative method.

What does 'confounding variable' mean in the context of EBD research?

Answer: A variable that correlates with both the independent and dependent variables, distorting results

Confounding variables can create false associations between design interventions and outcomes if not controlled.

Which of the following best describes a 'before-after' study design in healthcare design research?

Answer: Measuring outcomes in the same facility before and after a design intervention

Before-after designs compare outcomes at the same site pre- and post-intervention to assess design impact.

When EBD practitioners translate research into design decisions, what is the first recommended step?

Answer: Frame a clear question about the desired outcome

Framing a clear, focused question ensures the research search and design decisions remain aligned with the intended outcome.

A meta-analysis in EBD research is most useful because it:

Answer: Combines statistical results from multiple studies to increase power and precision

Meta-analyses pool quantitative data from many studies, yielding more reliable estimates of an intervention's effect.
