Presentations Research & Evidence-Based Practice 5

Question 1

A policy analyst presents survey data showing 70% of respondents support a new regulation. What critical methodological detail should be disclosed?

Accepted Answer

Survey response rate and how respondents were sampled

Answer

Low response rates or non-random sampling can introduce significant bias, making the 70% figure potentially unrepresentative of the broader population.

Question 2

During a Q&A, an audience member challenges your evidence with a conflicting study. What is the most professional response?

Accepted Answer

Acknowledge the study, note key methodological differences, and explain why your evidence is more applicable

Answer

Acknowledging conflicting evidence and explaining methodological differences demonstrates expertise and credibility while advancing the scholarly dialogue.

Question 3

What is publication bias and how should a presenter address it?

Accepted Answer

The tendency for positive results to be published more than null results; note this limitation when discussing the literature

Answer

Publication bias inflates perceived effect sizes in the literature; presenters should acknowledge it so audiences understand the evidence base may overestimate benefits.

Question 4

A presenter claims their intervention is 'evidence-based.' What minimum standard of evidence does this term typically require?

Accepted Answer

Support from at least one peer-reviewed study using an appropriate research design

Answer

'Evidence-based' minimally requires peer-reviewed research using rigorous methodology, though higher standards call for multiple studies and systematic reviews.

Question 5

Which approach best handles presenting preliminary or unpublished data to a scientific audience?

Accepted Answer

Label it clearly as preliminary and describe next validation steps

Answer

Clearly labeling data as preliminary and outlining validation steps is transparent and scientifically appropriate, preventing audiences from over-interpreting early findings.
