Evidence-Based Practice / Unit 22 EBP 3181 short lesson, about 20 seconds
Sampling Is a Design Decision
Captions available
The idea
How participants are selected is a design decision made in advance, and it determines who the answer can be said to apply to.
In practice
Two studies of the same intervention, one recruiting whoever volunteered and one drawing from a defined population.
Where people slip
Inclusion criteria say who is eligible. Sampling says how you choose among the eligible, and they are different decisions.
