How to Show Strong Personal Engagement
Choose a Topic That Excites You
Pick a research question that connects to your hobbies, interests, or curiosity. Examples:
- Modeling free-throw success in basketball.
- Analyzing patterns in your favorite music.
- Exploring how math predicts video game outcomes.
Your passion for the topic should be clear from your introduction.
