Question

Quizplus · Accepted Answer

Random assignment is the process of ensuring that all participants in an experiment have an equal chance of being assigned to any group. This helps to eliminate any potential bias or pre-existing differences between the groups before any intervention takes place. Single-blind and double-blind procedures involve keeping certain information hidden from either the participants (single-blind) or both the participants and the researchers (double-blind) to prevent bias. Observational research methods involve observing and recording behavior without any intervention or manipulation. While they can be useful in certain situations, they do not involve assigning participants to groups and therefore do not ensure equal groups before any intervention.
