Quasi-Experimental Designs
Captions available
The idea
A quasi-experimental design delivers an intervention and compares groups, but participants are not randomly assigned to those groups.
In practice
One ward receiving an intervention and another not, by choice rather than by chance.
Where people slip
Without random assignment the groups may differ before the intervention starts, and that difference can produce the result.
