Evidence-Based Practice / Unit 6 EBP 0779 short lesson, about 20 seconds
Nonexperimental Designs
Captions available
The idea
Nonexperimental designs observe without introducing an intervention, and can establish association rather than cause.
In practice
A study describing what happens in a population without changing anything about it.
Where people slip
Observation is not weakness. It is the only available option for questions where intervening would be impossible or unethical, and many important questions are of that kind.
