1. Create a thorough research plan.
2. Evaluate your hypothesis.

Why validity is more important than reliability?

How do you reduce bias in RCT?

The best way of eliminating selection bias, then, is by randomizing patients properly into groups. Randomization is achieved by using any method that gives every participant an equal chance to be allocated into any of the study groups.

Why is it important to remove bias in the selection of things?
