Expert writing Tips
Best practice
Use "models were selected" in formal writing where a passive voice is preferred, such as scientific papers or technical reports. This keeps the focus on the models rather than the selector.
Common error
Avoid overuse of the passive voice. While "models were selected" is grammatically correct, actively stating who selected the models (e.g., "the researchers selected the models") can often make your writing more direct and engaging.
