Accepted Answer

Applying laboratory or academic research findings to real-world design practice

Answer

Translational research bridges the gap between scientific findings and their practical application in design decisions.

Question 3

Which sampling method ensures every member of the population has an equal chance of selection?

Simple random sampling

Answer

Simple random sampling gives every individual an equal probability of inclusion, reducing selection bias.

Question 4
