What are the advantages of observational studies?
Observational studies are touted to possess several advantages in contrast to controlled and randomized trials such as reduced cost, time adherence, and the ability to evaluate a broad range of subjects .
What are the strengths and weaknesses of observations?
| Strengths: Weaknesses: | More natural behaviour occurs if people are unaware of observation. Observer may affect behaviour if detected. | Studying of animals that cannot be observed in captivity. Difficult to replicate – cannot control extraneous variables. |

How do you collect data through observations?
» Recording sheets and checklists are the most standardized way of collecting observation data and include both preset questions and responses.
