Evidence-Based Practice / Unit 4 EBP 0470 short lesson, about 20 seconds
Weighing a Body of Evidence
Captions available
The idea
A body of evidence is weighed on three things: how many studies it contains, the magnitude of the effect they report, and their consistency.
In practice
Nine studies, a moderate effect, and findings that point the same way.
Where people slip
One strong study is not a body of evidence. Number, size and agreement are three separate questions and are asked separately.
