📚 Topic Summary
Data storytelling is the art of presenting data in a compelling and understandable way. In AP Computer Science A (Java), this involves using Java code to process data and then visualize it or present it in a narrative format. Instead of just showing raw numbers, you explain what those numbers mean. This might involve creating charts, graphs, or interactive programs that highlight key trends and insights. Good data storytelling helps people understand complex information quickly and make better decisions.
This worksheet will guide you through the basics of data storytelling using Java. You'll learn some key vocabulary, practice filling in the blanks to solidify your understanding, and then tackle a critical thinking question to apply what you've learned.
