Question

What does randomization ensure in experimental research?

Answer 1

Hello!!

In randomized controlled trials, the research participants are assigned by chance, rather than by choice, to either the experimental group or the control group. Randomization reduces bias as much as possible. Randomization is designed to "control" (reduce or eliminate if possible) bias by all means.

Thanks!!
