Best answer

Randomization achieves good covariate balance in large samples. Good balance is guaranteed but poor for small samples. Strong ignorability automatically holds under randomization.

In randomized experiments, assignment mechanism is known and controlled by investigators. Strong ignorability automatically holds.

Randomization does:

  • balance observed covariates
  • balance unobserved covariates
  • balance potential outcomes, i.e. guarantee unconfoundedness
