Examples of active and passive voice in academic papers

📚 Quick Study Guide

• 🔍 Active voice emphasizes the actor performing the action (e.g., "The researcher conducted the experiment.").
• ✍️ Passive voice emphasizes the action or the recipient of the action (e.g., "The experiment was conducted by the researcher.").
• 💡 Use active voice for clarity and directness in most academic writing.
• 📊 Use passive voice when the actor is unknown, unimportant, or when you want to emphasize the action. For example, to describe a method: "The samples were analyzed using..."
• 📝 Be mindful of overuse of passive voice, as it can make writing sound vague and indirect.
• 🌍 Consider the conventions of your specific field. Some fields prefer passive voice in certain sections (e.g., methods).
• 🧐 To change a sentence from passive to active, identify the actor and make them the subject of the sentence.
