Research Methods & Evidence-Based Practice Flashcards

Which of the following best illustrates applying research skills before starting a tile installation?

Answer: Reviewing substrate preparation requirements, mortar type, and grout spacing specs in manufacturer documentation

Reviewing substrate prep, mortar compatibility, and joint specs from manufacturer documentation prevents installation failures and costly rework.

What is 'triangulation' in the context of construction research methodology?

Answer: Verifying findings by cross-referencing multiple independent authoritative sources

Triangulation strengthens conclusions by confirming information across multiple independent sources, reducing the risk of relying on a single flawed reference.

A homeowner claims that 'Grade 2' lumber is better than 'Grade 1' lumber because the number is higher. How should a knowledgeable handyman respond?

Answer: Explain that Grade 1 is actually higher quality, and research the grading standards to confirm appropriate use

Lumber grading is counterintuitive — lower numbers indicate higher quality; consulting grading standards prevents misapplication of materials.

What is the primary reason a handyman should keep a job log or field notes?

Answer: To create a factual record that supports troubleshooting, warranty claims, and future maintenance decisions

Accurate field notes document conditions, methods, and materials at the time of work, providing valuable evidence for future reference or dispute resolution.

Which of the following represents applying evidence-based practice when selecting adhesive for a subfloor repair?

Answer: Identifying the subfloor material, reviewing manufacturer compatibility charts, and selecting an adhesive rated for that substrate

Evidence-based material selection requires matching adhesive chemistry to specific substrate conditions using verified manufacturer compatibility data.

When a product's installation instructions conflict with local building code requirements, which takes precedence?

Answer: The local building code takes precedence, as it is legally enforceable

Local building codes are legally enforceable minimum standards; manufacturer instructions that fall short of code requirements do not provide legal protection.

What is the significance of a product's 'listing' by UL (Underwriters Laboratories) or a similar testing laboratory?

Answer: It indicates the product has been independently tested and certified to meet specific safety standards

A UL listing confirms independent third-party testing verifying the product meets defined safety and performance standards for its intended use.
