Study Notes
- An experimental study design is a type of research that uses controlled experiments to determine the cause and/or effect of a particular factor.
- In an experimental study, the investigator takes direct action to manipulate one or more factors in order to study the effects.
- There are three types of experimental study designs: clinical trial, field trial, and community trial.
- The aim of experimental study designs is to provide scientific proof of the etiological factors/risk factors.
- Blinding represents an important, distinct aspect of randomized controlled trials.
- Triple-blindness means that all participants, the doctor and the statistician are unaware of the group allocation.
- Only the principal investigator is aware of the group allocation and the treatment allocation.
