8. Controlled experiments can be randomized or nonrandomized.
True.
Step-by-step explanation:

Randomization is the process for assigning participants to treatment or control groups, not placebos. The reason for using a random chance procedure to assign subjects to treatment or control groups is to reduce bias.
