randomized trial
Lottery-based experiment
A randomized trial is an experiment where participants are assigned to different groups by chance rather than choice, typically to test whether a treatment works.
Random assignment helps ensure that differences in outcomes result from the treatment itself, not from preexisting differences between groups.
The randomized trial showed the vaccine reduced infections by 40 percent.
