Final answer:
For a 3-hour event, it's best to conduct a poll every 30 to 45 minutes, balancing participation with avoiding survey fatigue, while using well-crafted questions and diverse engagement techniques.
Step-by-step explanation:
During a 3-hour event, the frequency of pushing out polls to an audience should strike a balance between engaging participants and not overwhelming them. Considering the length of the event, conducting a poll every 30 to 45 minutes could be optimal. This frequency allows for participants to reflect on event content and provides immediate feedback without causing survey fatigue. Well-crafted questions ensure that participants do not feel led toward a certain answer and provide more accurate insights into the audience's opinions and preferences. Utilize diverse engagement techniques alongside polls, such as word clouds or small group discussions, to maintain a dynamic and interactive environment.
