Double-Blind

An experimental procedure in which neither the subjects of the experiment nor the persons administering the experiment know the critical aspects of the experiment, to prevent bias.

Single-Blind

A study or experiment design where only the participants are unaware of which group (experimental or control) they belong to, preventing bias in their responses.
