True Experimental Designs

The idea
In a true experimental design the intervention is randomly assigned to some participants and not to others.
In practice
Allocation decided by chance rather than by anyone's judgement.
Where people slip
Random assignment decides who gets what. It is not the same as random sampling, which decides who takes part.
