Evidence-Based Practice / Unit 6 EBP 0793 short lesson, about 20 seconds
The Sample in a Review Is Studies
Captions available
The idea
In a systematic review the sample is usually the number of studies rather than the number of participants.
In practice
A review reporting that it included eighteen studies covering four thousand people.
Where people slip
Both numbers matter and they answer different questions. Eighteen studies of twenty people each is not a large review.
